Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624192, here are decompositions:

179 + 31624013 = 31624192
191 + 31624001 = 31624192
233 + 31623959 = 31624192
239 + 31623953 = 31624192
263 + 31623929 = 31624192
461 + 31623731 = 31624192
491 + 31623701 = 31624192
521 + 31623671 = 31624192

Showing the first eight; more decompositions exist.
