Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615606, here are decompositions:

3 + 31615603 = 31615606
17 + 31615589 = 31615606
23 + 31615583 = 31615606
167 + 31615439 = 31615606
263 + 31615343 = 31615606
293 + 31615313 = 31615606
389 + 31615217 = 31615606
419 + 31615187 = 31615606

Showing the first eight; more decompositions exist.
