Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517426, here are decompositions:

13 + 31517413 = 31517426
19 + 31517407 = 31517426
37 + 31517389 = 31517426
229 + 31517197 = 31517426
277 + 31517149 = 31517426
433 + 31516993 = 31517426
547 + 31516879 = 31517426
607 + 31516819 = 31517426

Showing the first eight; more decompositions exist.
