Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448502, here are decompositions:

23 + 31448479 = 31448502
53 + 31448449 = 31448502
79 + 31448423 = 31448502
89 + 31448413 = 31448502
179 + 31448323 = 31448502
181 + 31448321 = 31448502
193 + 31448309 = 31448502
199 + 31448303 = 31448502

Showing the first eight; more decompositions exist.
