Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624498, here are decompositions:

41 + 31624457 = 31624498
131 + 31624367 = 31624498
149 + 31624349 = 31624498
167 + 31624331 = 31624498
281 + 31624217 = 31624498
509 + 31623989 = 31624498
569 + 31623929 = 31624498
641 + 31623857 = 31624498

Showing the first eight; more decompositions exist.
