Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597336, here are decompositions:

53 + 31597283 = 31597336
83 + 31597253 = 31597336
137 + 31597199 = 31597336
293 + 31597043 = 31597336
359 + 31596977 = 31597336
479 + 31596857 = 31597336
587 + 31596749 = 31597336
593 + 31596743 = 31597336

Showing the first eight; more decompositions exist.
