Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624228, here are decompositions:

11 + 31624217 = 31624228
101 + 31624127 = 31624228
227 + 31624001 = 31624228
239 + 31623989 = 31624228
257 + 31623971 = 31624228
269 + 31623959 = 31624228
281 + 31623947 = 31624228
431 + 31623797 = 31624228

Showing the first eight; more decompositions exist.
