Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496700, here are decompositions:

7 + 31496693 = 31496700
23 + 31496677 = 31496700
29 + 31496671 = 31496700
31 + 31496669 = 31496700
89 + 31496611 = 31496700
101 + 31496599 = 31496700
107 + 31496593 = 31496700
113 + 31496587 = 31496700

Showing the first eight; more decompositions exist.
