Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464266, here are decompositions:

73 + 31464193 = 31464266
79 + 31464187 = 31464266
199 + 31464067 = 31464266
307 + 31463959 = 31464266
373 + 31463893 = 31464266
409 + 31463857 = 31464266
439 + 31463827 = 31464266
487 + 31463779 = 31464266

Showing the first eight; more decompositions exist.
