Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467128, here are decompositions:

  • 61 + 31467067 = 31467128
  • 139 + 31466989 = 31467128
  • 151 + 31466977 = 31467128
  • 229 + 31466899 = 31467128
  • 271 + 31466857 = 31467128
  • 307 + 31466821 = 31467128
  • 337 + 31466791 = 31467128
  • 379 + 31466749 = 31467128

Showing the first eight; more decompositions exist.
