Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620148, here are decompositions:

  • 19 + 33620129 = 33620148
  • 97 + 33620051 = 33620148
  • 109 + 33620039 = 33620148
  • 167 + 33619981 = 33620148
  • 229 + 33619919 = 33620148
  • 337 + 33619811 = 33620148
  • 347 + 33619801 = 33620148
  • 349 + 33619799 = 33620148

Showing the first eight; more decompositions exist.
