Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623862, here are decompositions:

5 + 31623857 = 31623862
41 + 31623821 = 31623862
131 + 31623731 = 31623862
191 + 31623671 = 31623862
239 + 31623623 = 31623862
353 + 31623509 = 31623862
383 + 31623479 = 31623862
401 + 31623461 = 31623862

Showing the first eight; more decompositions exist.
