Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607270, here are decompositions:

7 + 31607263 = 31607270
43 + 31607227 = 31607270
223 + 31607047 = 31607270
307 + 31606963 = 31607270
313 + 31606957 = 31607270
367 + 31606903 = 31607270
613 + 31606657 = 31607270
619 + 31606651 = 31607270

Showing the first eight; more decompositions exist.
