Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466174, here are decompositions:

31 + 31466143 = 31466174
37 + 31466137 = 31466174
67 + 31466107 = 31466174
73 + 31466101 = 31466174
283 + 31465891 = 31466174
373 + 31465801 = 31466174
433 + 31465741 = 31466174
463 + 31465711 = 31466174

Showing the first eight; more decompositions exist.
