Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617958, here are decompositions:

5 + 31617953 = 31617958
17 + 31617941 = 31617958
59 + 31617899 = 31617958
131 + 31617827 = 31617958
269 + 31617689 = 31617958
461 + 31617497 = 31617958
509 + 31617449 = 31617958
587 + 31617371 = 31617958

Showing the first eight; more decompositions exist.
