Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615048, here are decompositions:

41 + 31615007 = 31615048
107 + 31614941 = 31615048
149 + 31614899 = 31615048
167 + 31614881 = 31615048
197 + 31614851 = 31615048
251 + 31614797 = 31615048
347 + 31614701 = 31615048
401 + 31614647 = 31615048

Showing the first eight; more decompositions exist.
