Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597004, here are decompositions:

7 + 31596997 = 31597004
13 + 31596991 = 31597004
97 + 31596907 = 31597004
157 + 31596847 = 31597004
211 + 31596793 = 31597004
331 + 31596673 = 31597004
367 + 31596637 = 31597004
421 + 31596583 = 31597004

Showing the first eight; more decompositions exist.
