Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489838, here are decompositions:

  • 17 + 2147489821 = 2147489838
  • 19 + 2147489819 = 2147489838
  • 41 + 2147489797 = 2147489838
  • 139 + 2147489699 = 2147489838
  • 199 + 2147489639 = 2147489838
  • 251 + 2147489587 = 2147489838
  • 397 + 2147489441 = 2147489838
  • 401 + 2147489437 = 2147489838

Showing the first eight; more decompositions exist.
