Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486926, here are decompositions:

67 + 31486859 = 31486926
73 + 31486853 = 31486926
157 + 31486769 = 31486926
193 + 31486733 = 31486926
199 + 31486727 = 31486926
269 + 31486657 = 31486926
283 + 31486643 = 31486926
293 + 31486633 = 31486926

Showing the first eight; more decompositions exist.
