Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486106, here are decompositions:

19 + 31486087 = 31486106
73 + 31486033 = 31486106
97 + 31486009 = 31486106
283 + 31485823 = 31486106
307 + 31485799 = 31486106
349 + 31485757 = 31486106
523 + 31485583 = 31486106
709 + 31485397 = 31486106

Showing the first eight; more decompositions exist.
