Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551796, here are decompositions:

113 + 31551683 = 31551796
167 + 31551629 = 31551796
197 + 31551599 = 31551796
257 + 31551539 = 31551796
293 + 31551503 = 31551796
359 + 31551437 = 31551796
383 + 31551413 = 31551796
389 + 31551407 = 31551796

Showing the first eight; more decompositions exist.
