Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481462, here are decompositions:

3 + 31481459 = 31481462
13 + 31481449 = 31481462
31 + 31481431 = 31481462
43 + 31481419 = 31481462
73 + 31481389 = 31481462
79 + 31481383 = 31481462
109 + 31481353 = 31481462
163 + 31481299 = 31481462

Showing the first eight; more decompositions exist.
