Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620594, here are decompositions:

13 + 31620581 = 31620594
17 + 31620577 = 31620594
23 + 31620571 = 31620594
73 + 31620521 = 31620594
97 + 31620497 = 31620594
107 + 31620487 = 31620594
113 + 31620481 = 31620594
151 + 31620443 = 31620594

Showing the first eight; more decompositions exist.
