Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448464, here are decompositions:

17 + 31448447 = 31448464
41 + 31448423 = 31448464
83 + 31448381 = 31448464
167 + 31448297 = 31448464
263 + 31448201 = 31448464
293 + 31448171 = 31448464
353 + 31448111 = 31448464
431 + 31448033 = 31448464

Showing the first eight; more decompositions exist.
