Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467236, here are decompositions:

7 + 31467229 = 31467236
37 + 31467199 = 31467236
67 + 31467169 = 31467236
79 + 31467157 = 31467236
103 + 31467133 = 31467236
109 + 31467127 = 31467236
337 + 31466899 = 31467236
379 + 31466857 = 31467236

Showing the first eight; more decompositions exist.
