Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607396, here are decompositions:

97 + 31607299 = 31607396
103 + 31607293 = 31607396
349 + 31607047 = 31607396
433 + 31606963 = 31607396
439 + 31606957 = 31607396
643 + 31606753 = 31607396
739 + 31606657 = 31607396
853 + 31606543 = 31607396

Showing the first eight; more decompositions exist.
