Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496600, here are decompositions:

7 + 31496593 = 31496600
13 + 31496587 = 31496600
61 + 31496539 = 31496600
151 + 31496449 = 31496600
181 + 31496419 = 31496600
211 + 31496389 = 31496600
229 + 31496371 = 31496600
271 + 31496329 = 31496600

Showing the first eight; more decompositions exist.
