Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624246, here are decompositions:

29 + 31624217 = 31624246
233 + 31624013 = 31624246
257 + 31623989 = 31624246
263 + 31623983 = 31624246
293 + 31623953 = 31624246
317 + 31623929 = 31624246
359 + 31623887 = 31624246
389 + 31623857 = 31624246

Showing the first eight; more decompositions exist.
