Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596418, here are decompositions:

5 + 31596413 = 31596418
17 + 31596401 = 31596418
101 + 31596317 = 31596418
107 + 31596311 = 31596418
389 + 31596029 = 31596418
449 + 31595969 = 31596418
587 + 31595831 = 31596418
641 + 31595777 = 31596418

Showing the first eight; more decompositions exist.
