Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551304, here are decompositions:

23 + 31551281 = 31551304
101 + 31551203 = 31551304
131 + 31551173 = 31551304
167 + 31551137 = 31551304
233 + 31551071 = 31551304
293 + 31551011 = 31551304
311 + 31550993 = 31551304
383 + 31550921 = 31551304

Showing the first eight; more decompositions exist.
