Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448942, here are decompositions:

43 + 31448899 = 31448942
79 + 31448863 = 31448942
103 + 31448839 = 31448942
139 + 31448803 = 31448942
223 + 31448719 = 31448942
229 + 31448713 = 31448942
409 + 31448533 = 31448942
463 + 31448479 = 31448942

Showing the first eight; more decompositions exist.
