Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461324, here are decompositions:

23 + 31461301 = 31461324
31 + 31461293 = 31461324
43 + 31461281 = 31461324
71 + 31461253 = 31461324
101 + 31461223 = 31461324
131 + 31461193 = 31461324
151 + 31461173 = 31461324
163 + 31461161 = 31461324

Showing the first eight; more decompositions exist.
