Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448524, here are decompositions:

5 + 31448519 = 31448524
17 + 31448507 = 31448524
101 + 31448423 = 31448524
227 + 31448297 = 31448524
353 + 31448171 = 31448524
383 + 31448141 = 31448524
467 + 31448057 = 31448524
491 + 31448033 = 31448524

Showing the first eight; more decompositions exist.
