Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479410, here are decompositions:

73 + 31479337 = 31479410
103 + 31479307 = 31479410
139 + 31479271 = 31479410
283 + 31479127 = 31479410
337 + 31479073 = 31479410
349 + 31479061 = 31479410
379 + 31479031 = 31479410
409 + 31479001 = 31479410

Showing the first eight; more decompositions exist.
