Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602242, here are decompositions:

3 + 31602239 = 31602242
79 + 31602163 = 31602242
163 + 31602079 = 31602242
193 + 31602049 = 31602242
379 + 31601863 = 31602242
433 + 31601809 = 31602242
499 + 31601743 = 31602242
571 + 31601671 = 31602242

Showing the first eight; more decompositions exist.
