Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624312, here are decompositions:

29 + 31624283 = 31624312
311 + 31624001 = 31624312
353 + 31623959 = 31624312
359 + 31623953 = 31624312
383 + 31623929 = 31624312
491 + 31623821 = 31624312
641 + 31623671 = 31624312
821 + 31623491 = 31624312

Showing the first eight; more decompositions exist.
