Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624234, here are decompositions:

17 + 31624217 = 31624234
107 + 31624127 = 31624234
233 + 31624001 = 31624234
251 + 31623983 = 31624234
263 + 31623971 = 31624234
281 + 31623953 = 31624234
347 + 31623887 = 31624234
503 + 31623731 = 31624234

Showing the first eight; more decompositions exist.
