Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523498, here are decompositions:

31 + 31523467 = 31523498
37 + 31523461 = 31523498
79 + 31523419 = 31523498
151 + 31523347 = 31523498
271 + 31523227 = 31523498
277 + 31523221 = 31523498
337 + 31523161 = 31523498
367 + 31523131 = 31523498

Showing the first eight; more decompositions exist.
