Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615036, here are decompositions:

23 + 31615013 = 31615036
29 + 31615007 = 31615036
83 + 31614953 = 31615036
107 + 31614929 = 31615036
137 + 31614899 = 31615036
197 + 31614839 = 31615036
239 + 31614797 = 31615036
359 + 31614677 = 31615036

Showing the first eight; more decompositions exist.
