Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614920, here are decompositions:

31 + 31614889 = 31614920
61 + 31614859 = 31614920
67 + 31614853 = 31614920
151 + 31614769 = 31614920
223 + 31614697 = 31614920
277 + 31614643 = 31614920
373 + 31614547 = 31614920
397 + 31614523 = 31614920

Showing the first eight; more decompositions exist.
