Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467974, here are decompositions:

7 + 31467967 = 31467974
37 + 31467937 = 31467974
127 + 31467847 = 31467974
163 + 31467811 = 31467974
211 + 31467763 = 31467974
283 + 31467691 = 31467974
541 + 31467433 = 31467974
607 + 31467367 = 31467974

Showing the first eight; more decompositions exist.
