Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467228, here are decompositions:

29 + 31467199 = 31467228
47 + 31467181 = 31467228
59 + 31467169 = 31467228
61 + 31467167 = 31467228
71 + 31467157 = 31467228
101 + 31467127 = 31467228
139 + 31467089 = 31467228
157 + 31467071 = 31467228

Showing the first eight; more decompositions exist.
