Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614906, here are decompositions:

7 + 31614899 = 31614906
17 + 31614889 = 31614906
47 + 31614859 = 31614906
53 + 31614853 = 31614906
67 + 31614839 = 31614906
73 + 31614833 = 31614906
109 + 31614797 = 31614906
137 + 31614769 = 31614906

Showing the first eight; more decompositions exist.
