Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574694, here are decompositions:

5 + 31574689 = 31574694
7 + 31574687 = 31574694
13 + 31574681 = 31574694
17 + 31574677 = 31574694
23 + 31574671 = 31574694
37 + 31574657 = 31574694
131 + 31574563 = 31574694
163 + 31574531 = 31574694

Showing the first eight; more decompositions exist.
