Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534166, here are decompositions:

109 + 31534057 = 31534166
199 + 31533967 = 31534166
337 + 31533829 = 31534166
397 + 31533769 = 31534166
619 + 31533547 = 31534166
757 + 31533409 = 31534166
787 + 31533379 = 31534166
823 + 31533343 = 31534166

Showing the first eight; more decompositions exist.
