Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399048, here are decompositions:

  • 31 + 2147399017 = 2147399048
  • 79 + 2147398969 = 2147399048
  • 199 + 2147398849 = 2147399048
  • 229 + 2147398819 = 2147399048
  • 367 + 2147398681 = 2147399048
  • 499 + 2147398549 = 2147399048
  • 541 + 2147398507 = 2147399048
  • 547 + 2147398501 = 2147399048

Showing the first eight; more decompositions exist.
