Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448344, here are decompositions:

23 + 31448321 = 31448344
41 + 31448303 = 31448344
47 + 31448297 = 31448344
173 + 31448171 = 31448344
233 + 31448111 = 31448344
311 + 31448033 = 31448344
383 + 31447961 = 31448344
443 + 31447901 = 31448344

Showing the first eight; more decompositions exist.
