Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465954, here are decompositions:

173 + 31465781 = 31465954
197 + 31465757 = 31465954
227 + 31465727 = 31465954
257 + 31465697 = 31465954
281 + 31465673 = 31465954
293 + 31465661 = 31465954
353 + 31465601 = 31465954
383 + 31465571 = 31465954

Showing the first eight; more decompositions exist.
