Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448214, here are decompositions:

13 + 31448201 = 31448214
23 + 31448191 = 31448214
43 + 31448171 = 31448214
53 + 31448161 = 31448214
73 + 31448141 = 31448214
103 + 31448111 = 31448214
157 + 31448057 = 31448214
181 + 31448033 = 31448214

Showing the first eight; more decompositions exist.
