Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602612, here are decompositions:

23 + 31602589 = 31602612
31 + 31602581 = 31602612
73 + 31602539 = 31602612
131 + 31602481 = 31602612
191 + 31602421 = 31602612
211 + 31602401 = 31602612
331 + 31602281 = 31602612
373 + 31602239 = 31602612

Showing the first eight; more decompositions exist.
