Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506482, here are decompositions:

3 + 31506479 = 31506482
61 + 31506421 = 31506482
109 + 31506373 = 31506482
151 + 31506331 = 31506482
199 + 31506283 = 31506482
211 + 31506271 = 31506482
379 + 31506103 = 31506482
421 + 31506061 = 31506482

Showing the first eight; more decompositions exist.
