Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448692, here are decompositions:

53 + 31448639 = 31448692
71 + 31448621 = 31448692
89 + 31448603 = 31448692
113 + 31448579 = 31448692
173 + 31448519 = 31448692
269 + 31448423 = 31448692
311 + 31448381 = 31448692
383 + 31448309 = 31448692

Showing the first eight; more decompositions exist.
