Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481594, here are decompositions:

3 + 31481591 = 31481594
73 + 31481521 = 31481594
97 + 31481497 = 31481594
163 + 31481431 = 31481594
211 + 31481383 = 31481594
223 + 31481371 = 31481594
241 + 31481353 = 31481594
631 + 31480963 = 31481594

Showing the first eight; more decompositions exist.
