Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591094, here are decompositions:

103 + 31590991 = 31591094
151 + 31590943 = 31591094
163 + 31590931 = 31591094
331 + 31590763 = 31591094
463 + 31590631 = 31591094
523 + 31590571 = 31591094
607 + 31590487 = 31591094
631 + 31590463 = 31591094

Showing the first eight; more decompositions exist.
