Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553498, here are decompositions:

139 + 31553359 = 31553498
337 + 31553161 = 31553498
409 + 31553089 = 31553498
421 + 31553077 = 31553498
499 + 31552999 = 31553498
607 + 31552891 = 31553498
619 + 31552879 = 31553498
751 + 31552747 = 31553498

Showing the first eight; more decompositions exist.
