Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85424, here are decompositions:

  • 13 + 85411 = 85424
  • 43 + 85381 = 85424
  • 61 + 85363 = 85424
  • 127 + 85297 = 85424
  • 181 + 85243 = 85424
  • 211 + 85213 = 85424
  • 223 + 85201 = 85424
  • 277 + 85147 = 85424

Showing the first eight; more decompositions exist.
