Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596394, here are decompositions:

3 + 31596391 = 31596394
83 + 31596311 = 31596394
101 + 31596293 = 31596394
251 + 31596143 = 31596394
353 + 31596041 = 31596394
521 + 31595873 = 31596394
563 + 31595831 = 31596394
587 + 31595807 = 31596394

Showing the first eight; more decompositions exist.
