Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489722, here are decompositions:

13 + 31489709 = 31489722
59 + 31489663 = 31489722
71 + 31489651 = 31489722
109 + 31489613 = 31489722
151 + 31489571 = 31489722
181 + 31489541 = 31489722
233 + 31489489 = 31489722
311 + 31489411 = 31489722

Showing the first eight; more decompositions exist.
