Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481692, here are decompositions:

71 + 31481621 = 31481692
83 + 31481609 = 31481692
101 + 31481591 = 31481692
149 + 31481543 = 31481692
233 + 31481459 = 31481692
239 + 31481453 = 31481692
443 + 31481249 = 31481692
461 + 31481231 = 31481692

Showing the first eight; more decompositions exist.
