Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614912, here are decompositions:

13 + 31614899 = 31614912
23 + 31614889 = 31614912
31 + 31614881 = 31614912
53 + 31614859 = 31614912
59 + 31614853 = 31614912
61 + 31614851 = 31614912
73 + 31614839 = 31614912
79 + 31614833 = 31614912

Showing the first eight; more decompositions exist.
