Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464670, here are decompositions:

53 + 31464617 = 31464670
89 + 31464581 = 31464670
113 + 31464557 = 31464670
227 + 31464443 = 31464670
269 + 31464401 = 31464670
311 + 31464359 = 31464670
389 + 31464281 = 31464670
401 + 31464269 = 31464670

Showing the first eight; more decompositions exist.
