Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624282, here are decompositions:

5 + 31624277 = 31624282
269 + 31624013 = 31624282
281 + 31624001 = 31624282
293 + 31623989 = 31624282
311 + 31623971 = 31624282
353 + 31623929 = 31624282
461 + 31623821 = 31624282
659 + 31623623 = 31624282

Showing the first eight; more decompositions exist.
