Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483798, here are decompositions:

107 + 31483691 = 31483798
149 + 31483649 = 31483798
251 + 31483547 = 31483798
491 + 31483307 = 31483798
569 + 31483229 = 31483798
701 + 31483097 = 31483798
821 + 31482977 = 31483798
977 + 31482821 = 31483798

Showing the first eight; more decompositions exist.
