Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602122, here are decompositions:

43 + 31602079 = 31602122
73 + 31602049 = 31602122
199 + 31601923 = 31602122
241 + 31601881 = 31602122
313 + 31601809 = 31602122
379 + 31601743 = 31602122
571 + 31601551 = 31602122
613 + 31601509 = 31602122

Showing the first eight; more decompositions exist.
