Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481046, here are decompositions:

7 + 31481039 = 31481046
73 + 31480973 = 31481046
83 + 31480963 = 31481046
97 + 31480949 = 31481046
127 + 31480919 = 31481046
167 + 31480879 = 31481046
173 + 31480873 = 31481046
197 + 31480849 = 31481046

Showing the first eight; more decompositions exist.
