Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448630, here are decompositions:

43 + 31448587 = 31448630
79 + 31448551 = 31448630
97 + 31448533 = 31448630
151 + 31448479 = 31448630
181 + 31448449 = 31448630
307 + 31448323 = 31448630
331 + 31448299 = 31448630
337 + 31448293 = 31448630

Showing the first eight; more decompositions exist.
