Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614900, here are decompositions:

11 + 31614889 = 31614900
19 + 31614881 = 31614900
41 + 31614859 = 31614900
47 + 31614853 = 31614900
61 + 31614839 = 31614900
67 + 31614833 = 31614900
71 + 31614829 = 31614900
103 + 31614797 = 31614900

Showing the first eight; more decompositions exist.
