Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448812, here are decompositions:

71 + 31448741 = 31448812
113 + 31448699 = 31448812
173 + 31448639 = 31448812
191 + 31448621 = 31448812
233 + 31448579 = 31448812
293 + 31448519 = 31448812
389 + 31448423 = 31448812
431 + 31448381 = 31448812

Showing the first eight; more decompositions exist.
