Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620674, here are decompositions:

13 + 31620661 = 31620674
73 + 31620601 = 31620674
97 + 31620577 = 31620674
103 + 31620571 = 31620674
157 + 31620517 = 31620674
193 + 31620481 = 31620674
277 + 31620397 = 31620674
331 + 31620343 = 31620674

Showing the first eight; more decompositions exist.
