Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553404, here are decompositions:

17 + 31553387 = 31553404
53 + 31553351 = 31553404
83 + 31553321 = 31553404
131 + 31553273 = 31553404
191 + 31553213 = 31553404
227 + 31553177 = 31553404
383 + 31553021 = 31553404
461 + 31552943 = 31553404

Showing the first eight; more decompositions exist.
