Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623652, here are decompositions:

29 + 31623623 = 31623652
131 + 31623521 = 31623652
173 + 31623479 = 31623652
191 + 31623461 = 31623652
443 + 31623209 = 31623652
479 + 31623173 = 31623652
701 + 31622951 = 31623652
719 + 31622933 = 31623652

Showing the first eight; more decompositions exist.
