Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464486, here are decompositions:

5 + 31464481 = 31464486
23 + 31464463 = 31464486
43 + 31464443 = 31464486
47 + 31464439 = 31464486
59 + 31464427 = 31464486
89 + 31464397 = 31464486
127 + 31464359 = 31464486
293 + 31464193 = 31464486

Showing the first eight; more decompositions exist.
