Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448492, here are decompositions:

13 + 31448479 = 31448492
43 + 31448449 = 31448492
79 + 31448413 = 31448492
193 + 31448299 = 31448492
199 + 31448293 = 31448492
211 + 31448281 = 31448492
331 + 31448161 = 31448492
421 + 31448071 = 31448492

Showing the first eight; more decompositions exist.
