Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465414, here are decompositions:

23 + 31465391 = 31465414
191 + 31465223 = 31465414
353 + 31465061 = 31465414
467 + 31464947 = 31465414
587 + 31464827 = 31465414
593 + 31464821 = 31465414
683 + 31464731 = 31465414
797 + 31464617 = 31465414

Showing the first eight; more decompositions exist.
