Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87372, here are decompositions:

  • 13 + 87359 = 87372
  • 59 + 87313 = 87372
  • 73 + 87299 = 87372
  • 79 + 87293 = 87372
  • 149 + 87223 = 87372
  • 151 + 87221 = 87372
  • 191 + 87181 = 87372
  • 193 + 87179 = 87372

Showing the first eight; more decompositions exist.
