Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489738, here are decompositions:

  • 151 + 2147489587 = 2147489738
  • 337 + 2147489401 = 2147489738
  • 439 + 2147489299 = 2147489738
  • 661 + 2147489077 = 2147489738
  • 997 + 2147488741 = 2147489738
  • 1321 + 2147488417 = 2147489738
  • 1327 + 2147488411 = 2147489738
  • 1459 + 2147488279 = 2147489738

Showing the first eight; more decompositions exist.
