Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507594, here are decompositions:

3 + 31507591 = 31507594
11 + 31507583 = 31507594
17 + 31507577 = 31507594
23 + 31507571 = 31507594
71 + 31507523 = 31507594
191 + 31507403 = 31507594
227 + 31507367 = 31507594
233 + 31507361 = 31507594

Showing the first eight; more decompositions exist.
