Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518632, here are decompositions:

31 + 31518601 = 31518632
43 + 31518589 = 31518632
109 + 31518523 = 31518632
151 + 31518481 = 31518632
181 + 31518451 = 31518632
331 + 31518301 = 31518632
373 + 31518259 = 31518632
571 + 31518061 = 31518632

Showing the first eight; more decompositions exist.
