Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607204, here are decompositions:

3 + 31607201 = 31607204
67 + 31607137 = 31607204
103 + 31607101 = 31607204
157 + 31607047 = 31607204
241 + 31606963 = 31607204
463 + 31606741 = 31607204
523 + 31606681 = 31607204
547 + 31606657 = 31607204

Showing the first eight; more decompositions exist.
