Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531602, here are decompositions:

23 + 31531579 = 31531602
79 + 31531523 = 31531602
131 + 31531471 = 31531602
149 + 31531453 = 31531602
181 + 31531421 = 31531602
199 + 31531403 = 31531602
233 + 31531369 = 31531602
331 + 31531271 = 31531602

Showing the first eight; more decompositions exist.
