Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448274, here are decompositions:

41 + 31448233 = 31448274
73 + 31448201 = 31448274
83 + 31448191 = 31448274
103 + 31448171 = 31448274
113 + 31448161 = 31448274
163 + 31448111 = 31448274
241 + 31448033 = 31448274
251 + 31448023 = 31448274

Showing the first eight; more decompositions exist.
