Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461594, here are decompositions:

23 + 31461571 = 31461594
37 + 31461557 = 31461594
41 + 31461553 = 31461594
61 + 31461533 = 31461594
71 + 31461523 = 31461594
107 + 31461487 = 31461594
113 + 31461481 = 31461594
137 + 31461457 = 31461594

Showing the first eight; more decompositions exist.
