Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530962, here are decompositions:

3 + 31530959 = 31530962
19 + 31530943 = 31530962
61 + 31530901 = 31530962
163 + 31530799 = 31530962
283 + 31530679 = 31530962
313 + 31530649 = 31530962
373 + 31530589 = 31530962
439 + 31530523 = 31530962

Showing the first eight; more decompositions exist.
