Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464570, here are decompositions:

13 + 31464557 = 31464570
23 + 31464547 = 31464570
61 + 31464509 = 31464570
89 + 31464481 = 31464570
107 + 31464463 = 31464570
127 + 31464443 = 31464570
131 + 31464439 = 31464570
149 + 31464421 = 31464570

Showing the first eight; more decompositions exist.
