Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467042, here are decompositions:

31 + 31467011 = 31467042
43 + 31466999 = 31467042
53 + 31466989 = 31467042
73 + 31466969 = 31467042
109 + 31466933 = 31467042
149 + 31466893 = 31467042
193 + 31466849 = 31467042
251 + 31466791 = 31467042

Showing the first eight; more decompositions exist.
