Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448936, here are decompositions:

37 + 31448899 = 31448936
73 + 31448863 = 31448936
97 + 31448839 = 31448936
223 + 31448713 = 31448936
229 + 31448707 = 31448936
349 + 31448587 = 31448936
457 + 31448479 = 31448936
487 + 31448449 = 31448936

Showing the first eight; more decompositions exist.
