Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620758, here are decompositions:

7 + 31620751 = 31620758
79 + 31620679 = 31620758
97 + 31620661 = 31620758
157 + 31620601 = 31620758
181 + 31620577 = 31620758
241 + 31620517 = 31620758
271 + 31620487 = 31620758
277 + 31620481 = 31620758

Showing the first eight; more decompositions exist.
