Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551496, here are decompositions:

59 + 31551437 = 31551496
83 + 31551413 = 31551496
89 + 31551407 = 31551496
149 + 31551347 = 31551496
167 + 31551329 = 31551496
293 + 31551203 = 31551496
359 + 31551137 = 31551496
503 + 31550993 = 31551496

Showing the first eight; more decompositions exist.
