Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464536, here are decompositions:

43 + 31464493 = 31464536
73 + 31464463 = 31464536
97 + 31464439 = 31464536
109 + 31464427 = 31464536
127 + 31464409 = 31464536
139 + 31464397 = 31464536
349 + 31464187 = 31464536
457 + 31464079 = 31464536

Showing the first eight; more decompositions exist.
