Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479368, here are decompositions:

31 + 31479337 = 31479368
61 + 31479307 = 31479368
79 + 31479289 = 31479368
97 + 31479271 = 31479368
127 + 31479241 = 31479368
241 + 31479127 = 31479368
307 + 31479061 = 31479368
337 + 31479031 = 31479368

Showing the first eight; more decompositions exist.
