Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465276, here are decompositions:

53 + 31465223 = 31465276
83 + 31465193 = 31465276
449 + 31464827 = 31465276
467 + 31464809 = 31465276
659 + 31464617 = 31465276
719 + 31464557 = 31465276
1229 + 31464047 = 31465276
1367 + 31463909 = 31465276

Showing the first eight; more decompositions exist.
