Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464740, here are decompositions:

31 + 31464709 = 31464740
163 + 31464577 = 31464740
193 + 31464547 = 31464740
277 + 31464463 = 31464740
313 + 31464427 = 31464740
331 + 31464409 = 31464740
547 + 31464193 = 31464740
661 + 31464079 = 31464740

Showing the first eight; more decompositions exist.
