Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623324, here are decompositions:

67 + 31623257 = 31623324
101 + 31623223 = 31623324
113 + 31623211 = 31623324
151 + 31623173 = 31623324
157 + 31623167 = 31623324
211 + 31623113 = 31623324
263 + 31623061 = 31623324
277 + 31623047 = 31623324

Showing the first eight; more decompositions exist.
