Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542924, here are decompositions:

13 + 31542911 = 31542924
43 + 31542881 = 31542924
47 + 31542877 = 31542924
67 + 31542857 = 31542924
97 + 31542827 = 31542924
113 + 31542811 = 31542924
137 + 31542787 = 31542924
157 + 31542767 = 31542924

Showing the first eight; more decompositions exist.
