Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551592, here are decompositions:

5 + 31551587 = 31551592
53 + 31551539 = 31551592
89 + 31551503 = 31551592
131 + 31551461 = 31551592
179 + 31551413 = 31551592
239 + 31551353 = 31551592
251 + 31551341 = 31551592
263 + 31551329 = 31551592

Showing the first eight; more decompositions exist.
