Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467388, here are decompositions:

41 + 31467347 = 31467388
59 + 31467329 = 31467388
137 + 31467251 = 31467388
317 + 31467071 = 31467388
389 + 31466999 = 31467388
419 + 31466969 = 31467388
521 + 31466867 = 31467388
761 + 31466627 = 31467388

Showing the first eight; more decompositions exist.
