Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498502, here are decompositions:

3 + 31498499 = 31498502
31 + 31498471 = 31498502
223 + 31498279 = 31498502
229 + 31498273 = 31498502
313 + 31498189 = 31498502
379 + 31498123 = 31498502
433 + 31498069 = 31498502
463 + 31498039 = 31498502

Showing the first eight; more decompositions exist.
