Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479404, here are decompositions:

67 + 31479337 = 31479404
97 + 31479307 = 31479404
127 + 31479277 = 31479404
163 + 31479241 = 31479404
277 + 31479127 = 31479404
331 + 31479073 = 31479404
373 + 31479031 = 31479404
421 + 31478983 = 31479404

Showing the first eight; more decompositions exist.
