Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614922, here are decompositions:

23 + 31614899 = 31614922
41 + 31614881 = 31614922
71 + 31614851 = 31614922
83 + 31614839 = 31614922
89 + 31614833 = 31614922
281 + 31614641 = 31614922
359 + 31614563 = 31614922
569 + 31614353 = 31614922

Showing the first eight; more decompositions exist.
