Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616652, here are decompositions:

5 + 31616647 = 31616652
29 + 31616623 = 31616652
73 + 31616579 = 31616652
83 + 31616569 = 31616652
113 + 31616539 = 31616652
131 + 31616521 = 31616652
173 + 31616479 = 31616652
229 + 31616423 = 31616652

Showing the first eight; more decompositions exist.
