Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542894, here are decompositions:

13 + 31542881 = 31542894
17 + 31542877 = 31542894
37 + 31542857 = 31542894
67 + 31542827 = 31542894
83 + 31542811 = 31542894
107 + 31542787 = 31542894
127 + 31542767 = 31542894
167 + 31542727 = 31542894

Showing the first eight; more decompositions exist.
