Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592402, here are decompositions:

13 + 31592389 = 31592402
199 + 31592203 = 31592402
229 + 31592173 = 31592402
241 + 31592161 = 31592402
349 + 31592053 = 31592402
409 + 31591993 = 31592402
619 + 31591783 = 31592402
691 + 31591711 = 31592402

Showing the first eight; more decompositions exist.
