Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464746, here are decompositions:

37 + 31464709 = 31464746
97 + 31464649 = 31464746
127 + 31464619 = 31464746
199 + 31464547 = 31464746
283 + 31464463 = 31464746
307 + 31464439 = 31464746
337 + 31464409 = 31464746
349 + 31464397 = 31464746

Showing the first eight; more decompositions exist.
