Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479356, here are decompositions:

19 + 31479337 = 31479356
67 + 31479289 = 31479356
79 + 31479277 = 31479356
229 + 31479127 = 31479356
283 + 31479073 = 31479356
373 + 31478983 = 31479356
397 + 31478959 = 31479356
619 + 31478737 = 31479356

Showing the first eight; more decompositions exist.
