Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620582, here are decompositions:

5 + 31620577 = 31620582
11 + 31620571 = 31620582
13 + 31620569 = 31620582
61 + 31620521 = 31620582
83 + 31620499 = 31620582
101 + 31620481 = 31620582
109 + 31620473 = 31620582
139 + 31620443 = 31620582

Showing the first eight; more decompositions exist.
