Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553444, here are decompositions:

61 + 31553383 = 31553444
211 + 31553233 = 31553444
283 + 31553161 = 31553444
367 + 31553077 = 31553444
613 + 31552831 = 31553444
751 + 31552693 = 31553444
823 + 31552621 = 31553444
907 + 31552537 = 31553444

Showing the first eight; more decompositions exist.
