Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600942, here are decompositions:

59 + 31600883 = 31600942
83 + 31600859 = 31600942
239 + 31600703 = 31600942
419 + 31600523 = 31600942
431 + 31600511 = 31600942
449 + 31600493 = 31600942
491 + 31600451 = 31600942
521 + 31600421 = 31600942

Showing the first eight; more decompositions exist.
