Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601852, here are decompositions:

3 + 31601849 = 31601852
43 + 31601809 = 31601852
109 + 31601743 = 31601852
181 + 31601671 = 31601852
223 + 31601629 = 31601852
283 + 31601569 = 31601852
313 + 31601539 = 31601852
379 + 31601473 = 31601852

Showing the first eight; more decompositions exist.
