Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448626, here are decompositions:

5 + 31448621 = 31448626
23 + 31448603 = 31448626
47 + 31448579 = 31448626
107 + 31448519 = 31448626
179 + 31448447 = 31448626
257 + 31448369 = 31448626
317 + 31448309 = 31448626
557 + 31448069 = 31448626

Showing the first eight; more decompositions exist.
