Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490092, here are decompositions:

3 + 31490089 = 31490092
149 + 31489943 = 31490092
173 + 31489919 = 31490092
191 + 31489901 = 31490092
251 + 31489841 = 31490092
383 + 31489709 = 31490092
419 + 31489673 = 31490092
479 + 31489613 = 31490092

Showing the first eight; more decompositions exist.
