Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464760, here are decompositions:

3 + 31464757 = 31464760
29 + 31464731 = 31464760
59 + 31464701 = 31464760
179 + 31464581 = 31464760
251 + 31464509 = 31464760
317 + 31464443 = 31464760
359 + 31464401 = 31464760
401 + 31464359 = 31464760

Showing the first eight; more decompositions exist.
