Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546974, here are decompositions:

5 + 31546969 = 31546974
37 + 31546937 = 31546974
61 + 31546913 = 31546974
83 + 31546891 = 31546974
113 + 31546861 = 31546974
127 + 31546847 = 31546974
131 + 31546843 = 31546974
157 + 31546817 = 31546974

Showing the first eight; more decompositions exist.
