Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467282, here are decompositions:

23 + 31467259 = 31467282
31 + 31467251 = 31467282
53 + 31467229 = 31467282
79 + 31467203 = 31467282
83 + 31467199 = 31467282
101 + 31467181 = 31467282
113 + 31467169 = 31467282
149 + 31467133 = 31467282

Showing the first eight; more decompositions exist.
