Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448776, here are decompositions:

59 + 31448717 = 31448776
83 + 31448693 = 31448776
137 + 31448639 = 31448776
173 + 31448603 = 31448776
197 + 31448579 = 31448776
257 + 31448519 = 31448776
269 + 31448507 = 31448776
353 + 31448423 = 31448776

Showing the first eight; more decompositions exist.
