Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607262, here are decompositions:

61 + 31607201 = 31607262
109 + 31607153 = 31607262
223 + 31607039 = 31607262
283 + 31606979 = 31607262
311 + 31606951 = 31607262
331 + 31606931 = 31607262
359 + 31606903 = 31607262
383 + 31606879 = 31607262

Showing the first eight; more decompositions exist.
