Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465006, here are decompositions:

3 + 31465003 = 31465006
59 + 31464947 = 31465006
179 + 31464827 = 31465006
197 + 31464809 = 31465006
389 + 31464617 = 31465006
449 + 31464557 = 31465006
563 + 31464443 = 31465006
647 + 31464359 = 31465006

Showing the first eight; more decompositions exist.
