Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553674, here are decompositions:

3 + 31553671 = 31553674
11 + 31553663 = 31553674
353 + 31553321 = 31553674
401 + 31553273 = 31553674
461 + 31553213 = 31553674
491 + 31553183 = 31553674
653 + 31553021 = 31553674
821 + 31552853 = 31553674

Showing the first eight; more decompositions exist.
