Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551484, here are decompositions:

23 + 31551461 = 31551484
47 + 31551437 = 31551484
53 + 31551431 = 31551484
71 + 31551413 = 31551484
131 + 31551353 = 31551484
137 + 31551347 = 31551484
281 + 31551203 = 31551484
311 + 31551173 = 31551484

Showing the first eight; more decompositions exist.
