Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596830, here are decompositions:

37 + 31596793 = 31596830
61 + 31596769 = 31596830
73 + 31596757 = 31596830
79 + 31596751 = 31596830
151 + 31596679 = 31596830
157 + 31596673 = 31596830
193 + 31596637 = 31596830
277 + 31596553 = 31596830

Showing the first eight; more decompositions exist.
