Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465774, here are decompositions:

17 + 31465757 = 31465774
47 + 31465727 = 31465774
101 + 31465673 = 31465774
113 + 31465661 = 31465774
173 + 31465601 = 31465774
227 + 31465547 = 31465774
293 + 31465481 = 31465774
383 + 31465391 = 31465774

Showing the first eight; more decompositions exist.
