Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528324, here are decompositions:

11 + 31528313 = 31528324
41 + 31528283 = 31528324
83 + 31528241 = 31528324
167 + 31528157 = 31528324
173 + 31528151 = 31528324
197 + 31528127 = 31528324
257 + 31528067 = 31528324
383 + 31527941 = 31528324

Showing the first eight; more decompositions exist.
