Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553324, here are decompositions:

3 + 31553321 = 31553324
163 + 31553161 = 31553324
307 + 31553017 = 31553324
433 + 31552891 = 31553324
577 + 31552747 = 31553324
631 + 31552693 = 31553324
643 + 31552681 = 31553324
787 + 31552537 = 31553324

Showing the first eight; more decompositions exist.
