Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553654, here are decompositions:

37 + 31553617 = 31553654
127 + 31553527 = 31553654
151 + 31553503 = 31553654
271 + 31553383 = 31553654
421 + 31553233 = 31553654
577 + 31553077 = 31553654
823 + 31552831 = 31553654
907 + 31552747 = 31553654

Showing the first eight; more decompositions exist.
