Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492424, here are decompositions:

3 + 31492421 = 31492424
31 + 31492393 = 31492424
163 + 31492261 = 31492424
181 + 31492243 = 31492424
211 + 31492213 = 31492424
331 + 31492093 = 31492424
373 + 31492051 = 31492424
631 + 31491793 = 31492424

Showing the first eight; more decompositions exist.
