Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614544, here are decompositions:

167 + 31614377 = 31614544
173 + 31614371 = 31614544
191 + 31614353 = 31614544
317 + 31614227 = 31614544
347 + 31614197 = 31614544
383 + 31614161 = 31614544
617 + 31613927 = 31614544
677 + 31613867 = 31614544

Showing the first eight; more decompositions exist.
