Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177842, here are decompositions:

  • 3 + 177839 = 177842
  • 19 + 177823 = 177842
  • 31 + 177811 = 177842
  • 79 + 177763 = 177842
  • 103 + 177739 = 177842
  • 151 + 177691 = 177842
  • 163 + 177679 = 177842
  • 241 + 177601 = 177842

Showing the first eight; more decompositions exist.
