Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510694, here are decompositions:

3 + 31510691 = 31510694
13 + 31510681 = 31510694
37 + 31510657 = 31510694
67 + 31510627 = 31510694
307 + 31510387 = 31510694
331 + 31510363 = 31510694
373 + 31510321 = 31510694
601 + 31510093 = 31510694

Showing the first eight; more decompositions exist.
