Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479214, here are decompositions:

  • 17 + 31479197 = 31479214
  • 83 + 31479131 = 31479214
  • 113 + 31479101 = 31479214
  • 131 + 31479083 = 31479214
  • 197 + 31479017 = 31479214
  • 257 + 31478957 = 31479214
  • 281 + 31478933 = 31479214
  • 383 + 31478831 = 31479214

Showing the first eight; more decompositions exist.
