Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623330, here are decompositions:

73 + 31623257 = 31623330
107 + 31623223 = 31623330
131 + 31623199 = 31623330
149 + 31623181 = 31623330
157 + 31623173 = 31623330
163 + 31623167 = 31623330
269 + 31623061 = 31623330
283 + 31623047 = 31623330

Showing the first eight; more decompositions exist.
