Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448836, here are decompositions:

137 + 31448699 = 31448836
197 + 31448639 = 31448836
233 + 31448603 = 31448836
257 + 31448579 = 31448836
317 + 31448519 = 31448836
389 + 31448447 = 31448836
467 + 31448369 = 31448836
983 + 31447853 = 31448836

Showing the first eight; more decompositions exist.
