Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448462, here are decompositions:

13 + 31448449 = 31448462
139 + 31448323 = 31448462
163 + 31448299 = 31448462
181 + 31448281 = 31448462
229 + 31448233 = 31448462
271 + 31448191 = 31448462
313 + 31448149 = 31448462
439 + 31448023 = 31448462

Showing the first eight; more decompositions exist.
