Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448446, here are decompositions:

23 + 31448423 = 31448446
137 + 31448309 = 31448446
149 + 31448297 = 31448446
389 + 31448057 = 31448446
479 + 31447967 = 31448446
593 + 31447853 = 31448446
647 + 31447799 = 31448446
677 + 31447769 = 31448446

Showing the first eight; more decompositions exist.
