Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541700, here are decompositions:

7 + 31541693 = 31541700
23 + 31541677 = 31541700
41 + 31541659 = 31541700
67 + 31541633 = 31541700
89 + 31541611 = 31541700
103 + 31541597 = 31541700
109 + 31541591 = 31541700
131 + 31541569 = 31541700

Showing the first eight; more decompositions exist.
