Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481846, here are decompositions:

3 + 31481843 = 31481846
79 + 31481767 = 31481846
103 + 31481743 = 31481846
163 + 31481683 = 31481846
223 + 31481623 = 31481846
337 + 31481509 = 31481846
349 + 31481497 = 31481846
367 + 31481479 = 31481846

Showing the first eight; more decompositions exist.
