Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540490, here are decompositions:

  • 29 + 33540461 = 33540490
  • 131 + 33540359 = 33540490
  • 173 + 33540317 = 33540490
  • 233 + 33540257 = 33540490
  • 239 + 33540251 = 33540490
  • 251 + 33540239 = 33540490
  • 281 + 33540209 = 33540490
  • 383 + 33540107 = 33540490

Showing the first eight; more decompositions exist.
