Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479182, here are decompositions:

109 + 31479073 = 31479182
151 + 31479031 = 31479182
181 + 31479001 = 31479182
199 + 31478983 = 31479182
223 + 31478959 = 31479182
271 + 31478911 = 31479182
331 + 31478851 = 31479182
463 + 31478719 = 31479182

Showing the first eight; more decompositions exist.
