Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467296, here are decompositions:

37 + 31467259 = 31467296
67 + 31467229 = 31467296
97 + 31467199 = 31467296
127 + 31467169 = 31467296
139 + 31467157 = 31467296
163 + 31467133 = 31467296
193 + 31467103 = 31467296
229 + 31467067 = 31467296

Showing the first eight; more decompositions exist.
