Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482926, here are decompositions:

19 + 31482907 = 31482926
37 + 31482889 = 31482926
67 + 31482859 = 31482926
103 + 31482823 = 31482926
127 + 31482799 = 31482926
283 + 31482643 = 31482926
313 + 31482613 = 31482926
367 + 31482559 = 31482926

Showing the first eight; more decompositions exist.
