Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607230, here are decompositions:

3 + 31607227 = 31607230
23 + 31607207 = 31607230
29 + 31607201 = 31607230
191 + 31607039 = 31607230
233 + 31606997 = 31607230
251 + 31606979 = 31607230
257 + 31606973 = 31607230
311 + 31606919 = 31607230

Showing the first eight; more decompositions exist.
