Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623624, here are decompositions:

7 + 31623617 = 31623624
17 + 31623607 = 31623624
101 + 31623523 = 31623624
103 + 31623521 = 31623624
113 + 31623511 = 31623624
127 + 31623497 = 31623624
163 + 31623461 = 31623624
181 + 31623443 = 31623624

Showing the first eight; more decompositions exist.
