Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616700, here are decompositions:

7 + 31616693 = 31616700
13 + 31616687 = 31616700
23 + 31616677 = 31616700
29 + 31616671 = 31616700
53 + 31616647 = 31616700
97 + 31616603 = 31616700
131 + 31616569 = 31616700
139 + 31616561 = 31616700

Showing the first eight; more decompositions exist.
