Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486954, here are decompositions:

101 + 31486853 = 31486954
227 + 31486727 = 31486954
293 + 31486661 = 31486954
311 + 31486643 = 31486954
383 + 31486571 = 31486954
461 + 31486493 = 31486954
491 + 31486463 = 31486954
503 + 31486451 = 31486954

Showing the first eight; more decompositions exist.
