Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489450, here are decompositions:

  • 13 + 2147489437 = 2147489450
  • 103 + 2147489347 = 2147489450
  • 151 + 2147489299 = 2147489450
  • 307 + 2147489143 = 2147489450
  • 367 + 2147489083 = 2147489450
  • 373 + 2147489077 = 2147489450
  • 433 + 2147489017 = 2147489450
  • 709 + 2147488741 = 2147489450

Showing the first eight; more decompositions exist.
