Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489710, here are decompositions:

37 + 31489673 = 31489710
47 + 31489663 = 31489710
59 + 31489651 = 31489710
97 + 31489613 = 31489710
139 + 31489571 = 31489710
191 + 31489519 = 31489710
277 + 31489433 = 31489710
283 + 31489427 = 31489710

Showing the first eight; more decompositions exist.
