Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479300, here are decompositions:

11 + 31479289 = 31479300
23 + 31479277 = 31479300
29 + 31479271 = 31479300
31 + 31479269 = 31479300
59 + 31479241 = 31479300
103 + 31479197 = 31479300
173 + 31479127 = 31479300
199 + 31479101 = 31479300

Showing the first eight; more decompositions exist.
