Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448654, here are decompositions:

7 + 31448647 = 31448654
67 + 31448587 = 31448654
73 + 31448581 = 31448654
103 + 31448551 = 31448654
241 + 31448413 = 31448654
277 + 31448377 = 31448654
331 + 31448323 = 31448654
373 + 31448281 = 31448654

Showing the first eight; more decompositions exist.
