Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615062, here are decompositions:

23 + 31615039 = 31615062
109 + 31614953 = 31615062
163 + 31614899 = 31615062
173 + 31614889 = 31615062
181 + 31614881 = 31615062
211 + 31614851 = 31615062
223 + 31614839 = 31615062
229 + 31614833 = 31615062

Showing the first eight; more decompositions exist.
