Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465548, here are decompositions:

19 + 31465529 = 31465548
67 + 31465481 = 31465548
89 + 31465459 = 31465548
97 + 31465451 = 31465548
131 + 31465417 = 31465548
157 + 31465391 = 31465548
227 + 31465321 = 31465548
239 + 31465309 = 31465548

Showing the first eight; more decompositions exist.
