Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624252, here are decompositions:

239 + 31624013 = 31624252
251 + 31624001 = 31624252
263 + 31623989 = 31624252
269 + 31623983 = 31624252
281 + 31623971 = 31624252
293 + 31623959 = 31624252
431 + 31623821 = 31624252
521 + 31623731 = 31624252

Showing the first eight; more decompositions exist.
