Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588094, here are decompositions:

7 + 31588087 = 31588094
151 + 31587943 = 31588094
277 + 31587817 = 31588094
313 + 31587781 = 31588094
397 + 31587697 = 31588094
661 + 31587433 = 31588094
673 + 31587421 = 31588094
823 + 31587271 = 31588094

Showing the first eight; more decompositions exist.
