Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627318, here are decompositions:

  • 29 + 31627289 = 31627318
  • 71 + 31627247 = 31627318
  • 101 + 31627217 = 31627318
  • 167 + 31627151 = 31627318
  • 197 + 31627121 = 31627318
  • 227 + 31627091 = 31627318
  • 311 + 31627007 = 31627318
  • 419 + 31626899 = 31627318

Showing the first eight; more decompositions exist.
