Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476926, here are decompositions:

73 + 31476853 = 31476926
79 + 31476847 = 31476926
97 + 31476829 = 31476926
127 + 31476799 = 31476926
193 + 31476733 = 31476926
199 + 31476727 = 31476926
223 + 31476703 = 31476926
379 + 31476547 = 31476926

Showing the first eight; more decompositions exist.
