Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592038, here are decompositions:

41 + 31591997 = 31592038
59 + 31591979 = 31592038
389 + 31591649 = 31592038
461 + 31591577 = 31592038
521 + 31591517 = 31592038
617 + 31591421 = 31592038
701 + 31591337 = 31592038
839 + 31591199 = 31592038

Showing the first eight; more decompositions exist.
