Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553804, here are decompositions:

3 + 31553801 = 31553804
43 + 31553761 = 31553804
97 + 31553707 = 31553804
277 + 31553527 = 31553804
421 + 31553383 = 31553804
571 + 31553233 = 31553804
643 + 31553161 = 31553804
727 + 31553077 = 31553804

Showing the first eight; more decompositions exist.
