Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489692, here are decompositions:

19 + 31489673 = 31489692
29 + 31489663 = 31489692
41 + 31489651 = 31489692
79 + 31489613 = 31489692
151 + 31489541 = 31489692
173 + 31489519 = 31489692
229 + 31489463 = 31489692
281 + 31489411 = 31489692

Showing the first eight; more decompositions exist.
