Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601152, here are decompositions:

53 + 31601099 = 31601152
101 + 31601051 = 31601152
269 + 31600883 = 31601152
293 + 31600859 = 31601152
353 + 31600799 = 31601152
419 + 31600733 = 31601152
431 + 31600721 = 31601152
449 + 31600703 = 31601152

Showing the first eight; more decompositions exist.
