Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480276, here are decompositions:

17 + 31480259 = 31480276
173 + 31480103 = 31480276
197 + 31480079 = 31480276
227 + 31480049 = 31480276
257 + 31480019 = 31480276
419 + 31479857 = 31480276
557 + 31479719 = 31480276
683 + 31479593 = 31480276

Showing the first eight; more decompositions exist.
