Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489414, here are decompositions:

3 + 31489411 = 31489414
23 + 31489391 = 31489414
167 + 31489247 = 31489414
197 + 31489217 = 31489414
233 + 31489181 = 31489414
317 + 31489097 = 31489414
443 + 31488971 = 31489414
503 + 31488911 = 31489414

Showing the first eight; more decompositions exist.
