Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448612, here are decompositions:

31 + 31448581 = 31448612
61 + 31448551 = 31448612
79 + 31448533 = 31448612
163 + 31448449 = 31448612
199 + 31448413 = 31448612
313 + 31448299 = 31448612
331 + 31448281 = 31448612
379 + 31448233 = 31448612

Showing the first eight; more decompositions exist.
