Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615576, here are decompositions:

137 + 31615439 = 31615576
173 + 31615403 = 31615576
233 + 31615343 = 31615576
263 + 31615313 = 31615576
347 + 31615229 = 31615576
359 + 31615217 = 31615576
383 + 31615193 = 31615576
389 + 31615187 = 31615576

Showing the first eight; more decompositions exist.
