Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623202, here are decompositions:

3 + 31623199 = 31623202
29 + 31623173 = 31623202
89 + 31623113 = 31623202
179 + 31623023 = 31623202
251 + 31622951 = 31623202
263 + 31622939 = 31623202
269 + 31622933 = 31623202
461 + 31622741 = 31623202

Showing the first eight; more decompositions exist.
