Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607588, here are decompositions:

7 + 31607581 = 31607588
37 + 31607551 = 31607588
127 + 31607461 = 31607588
139 + 31607449 = 31607588
307 + 31607281 = 31607588
487 + 31607101 = 31607588
541 + 31607047 = 31607588
631 + 31606957 = 31607588

Showing the first eight; more decompositions exist.
