Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574698, here are decompositions:

5 + 31574693 = 31574698
11 + 31574687 = 31574698
17 + 31574681 = 31574698
41 + 31574657 = 31574698
59 + 31574639 = 31574698
167 + 31574531 = 31574698
191 + 31574507 = 31574698
269 + 31574429 = 31574698

Showing the first eight; more decompositions exist.
