Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485426, here are decompositions:

19 + 31485407 = 31485426
29 + 31485397 = 31485426
43 + 31485383 = 31485426
47 + 31485379 = 31485426
67 + 31485359 = 31485426
73 + 31485353 = 31485426
107 + 31485319 = 31485426
113 + 31485313 = 31485426

Showing the first eight; more decompositions exist.
