Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448244, here are decompositions:

11 + 31448233 = 31448244
43 + 31448201 = 31448244
53 + 31448191 = 31448244
73 + 31448171 = 31448244
83 + 31448161 = 31448244
103 + 31448141 = 31448244
173 + 31448071 = 31448244
211 + 31448033 = 31448244

Showing the first eight; more decompositions exist.
