Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607276, here are decompositions:

13 + 31607263 = 31607276
139 + 31607137 = 31607276
229 + 31607047 = 31607276
313 + 31606963 = 31607276
373 + 31606903 = 31607276
397 + 31606879 = 31607276
523 + 31606753 = 31607276
619 + 31606657 = 31607276

Showing the first eight; more decompositions exist.
