Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479190, here are decompositions:

  • 59 + 31479131 = 31479190
  • 89 + 31479101 = 31479190
  • 107 + 31479083 = 31479190
  • 173 + 31479017 = 31479190
  • 233 + 31478957 = 31479190
  • 257 + 31478933 = 31479190
  • 359 + 31478831 = 31479190
  • 383 + 31478807 = 31479190

Showing the first eight; more decompositions exist.
