Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467158, here are decompositions:

31 + 31467127 = 31467158
181 + 31466977 = 31467158
337 + 31466821 = 31467158
367 + 31466791 = 31467158
409 + 31466749 = 31467158
439 + 31466719 = 31467158
487 + 31466671 = 31467158
571 + 31466587 = 31467158

Showing the first eight; more decompositions exist.
