Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494600, here are decompositions:

17 + 31494583 = 31494600
19 + 31494581 = 31494600
47 + 31494553 = 31494600
97 + 31494503 = 31494600
103 + 31494497 = 31494600
131 + 31494469 = 31494600
157 + 31494443 = 31494600
173 + 31494427 = 31494600

Showing the first eight; more decompositions exist.
