Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480060, here are decompositions:

11 + 31480049 = 31480060
41 + 31480019 = 31480060
113 + 31479947 = 31480060
179 + 31479881 = 31480060
239 + 31479821 = 31480060
257 + 31479803 = 31480060
317 + 31479743 = 31480060
389 + 31479671 = 31480060

Showing the first eight; more decompositions exist.
