Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618058, here are decompositions:

61 + 31617997 = 31618058
97 + 31617961 = 31618058
181 + 31617877 = 31618058
379 + 31617679 = 31618058
499 + 31617559 = 31618058
601 + 31617457 = 31618058
859 + 31617199 = 31618058
877 + 31617181 = 31618058

Showing the first eight; more decompositions exist.
