Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624108, here are decompositions:

107 + 31624001 = 31624108
137 + 31623971 = 31624108
149 + 31623959 = 31624108
179 + 31623929 = 31624108
251 + 31623857 = 31624108
311 + 31623797 = 31624108
401 + 31623707 = 31624108
491 + 31623617 = 31624108

Showing the first eight; more decompositions exist.
