Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572926, here are decompositions:

103 + 31572823 = 31572926
157 + 31572769 = 31572926
163 + 31572763 = 31572926
193 + 31572733 = 31572926
199 + 31572727 = 31572926
277 + 31572649 = 31572926
337 + 31572589 = 31572926
367 + 31572559 = 31572926

Showing the first eight; more decompositions exist.
