Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493846, here are decompositions:

67 + 31493779 = 31493846
103 + 31493743 = 31493846
157 + 31493689 = 31493846
193 + 31493653 = 31493846
277 + 31493569 = 31493846
313 + 31493533 = 31493846
379 + 31493467 = 31493846
499 + 31493347 = 31493846

Showing the first eight; more decompositions exist.
