Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742408, here are decompositions:

  • 7 + 8742401 = 8742408
  • 29 + 8742379 = 8742408
  • 41 + 8742367 = 8742408
  • 61 + 8742347 = 8742408
  • 149 + 8742259 = 8742408
  • 211 + 8742197 = 8742408
  • 239 + 8742169 = 8742408
  • 251 + 8742157 = 8742408

Showing the first eight; more decompositions exist.
