Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574700, here are decompositions:

7 + 31574693 = 31574700
11 + 31574689 = 31574700
13 + 31574687 = 31574700
19 + 31574681 = 31574700
23 + 31574677 = 31574700
29 + 31574671 = 31574700
43 + 31574657 = 31574700
61 + 31574639 = 31574700

Showing the first eight; more decompositions exist.
