Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506362, here are decompositions:

3 + 31506359 = 31506362
31 + 31506331 = 31506362
79 + 31506283 = 31506362
271 + 31506091 = 31506362
331 + 31506031 = 31506362
373 + 31505989 = 31506362
379 + 31505983 = 31506362
439 + 31505923 = 31506362

Showing the first eight; more decompositions exist.
