Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465254, here are decompositions:

11 + 31465243 = 31465254
31 + 31465223 = 31465254
61 + 31465193 = 31465254
71 + 31465183 = 31465254
101 + 31465153 = 31465254
131 + 31465123 = 31465254
193 + 31465061 = 31465254
251 + 31465003 = 31465254

Showing the first eight; more decompositions exist.
