Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448624, here are decompositions:

3 + 31448621 = 31448624
37 + 31448587 = 31448624
43 + 31448581 = 31448624
73 + 31448551 = 31448624
211 + 31448413 = 31448624
331 + 31448293 = 31448624
433 + 31448191 = 31448624
463 + 31448161 = 31448624

Showing the first eight; more decompositions exist.
