Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615060, here are decompositions:

47 + 31615013 = 31615060
53 + 31615007 = 31615060
107 + 31614953 = 31615060
131 + 31614929 = 31615060
179 + 31614881 = 31615060
227 + 31614833 = 31615060
263 + 31614797 = 31615060
353 + 31614707 = 31615060

Showing the first eight; more decompositions exist.
