Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615348, here are decompositions:

5 + 31615343 = 31615348
131 + 31615217 = 31615348
137 + 31615211 = 31615348
179 + 31615169 = 31615348
239 + 31615109 = 31615348
251 + 31615097 = 31615348
419 + 31614929 = 31615348
449 + 31614899 = 31615348

Showing the first eight; more decompositions exist.
