Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464582, here are decompositions:

5 + 31464577 = 31464582
11 + 31464571 = 31464582
73 + 31464509 = 31464582
89 + 31464493 = 31464582
101 + 31464481 = 31464582
131 + 31464451 = 31464582
139 + 31464443 = 31464582
173 + 31464409 = 31464582

Showing the first eight; more decompositions exist.
