Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448894, here are decompositions:

3 + 31448891 = 31448894
31 + 31448863 = 31448894
73 + 31448821 = 31448894
181 + 31448713 = 31448894
307 + 31448587 = 31448894
313 + 31448581 = 31448894
571 + 31448323 = 31448894
601 + 31448293 = 31448894

Showing the first eight; more decompositions exist.
