Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489762, here are decompositions:

11 + 31489751 = 31489762
41 + 31489721 = 31489762
53 + 31489709 = 31489762
89 + 31489673 = 31489762
149 + 31489613 = 31489762
191 + 31489571 = 31489762
503 + 31489259 = 31489762
569 + 31489193 = 31489762

Showing the first eight; more decompositions exist.
