Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496774, here are decompositions:

97 + 31496677 = 31496774
103 + 31496671 = 31496774
163 + 31496611 = 31496774
181 + 31496593 = 31496774
223 + 31496551 = 31496774
457 + 31496317 = 31496774
601 + 31496173 = 31496774
613 + 31496161 = 31496774

Showing the first eight; more decompositions exist.
