Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616582, here are decompositions:

3 + 31616579 = 31616582
13 + 31616569 = 31616582
43 + 31616539 = 31616582
61 + 31616521 = 31616582
73 + 31616509 = 31616582
103 + 31616479 = 31616582
163 + 31616419 = 31616582
181 + 31616401 = 31616582

Showing the first eight; more decompositions exist.
