Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571762, here are decompositions:

31 + 31571731 = 31571762
109 + 31571653 = 31571762
151 + 31571611 = 31571762
193 + 31571569 = 31571762
349 + 31571413 = 31571762
373 + 31571389 = 31571762
379 + 31571383 = 31571762
571 + 31571191 = 31571762

Showing the first eight; more decompositions exist.
