Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464488, here are decompositions:

7 + 31464481 = 31464488
37 + 31464451 = 31464488
61 + 31464427 = 31464488
67 + 31464421 = 31464488
79 + 31464409 = 31464488
409 + 31464079 = 31464488
421 + 31464067 = 31464488
457 + 31464031 = 31464488

Showing the first eight; more decompositions exist.
