Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553794, here are decompositions:

11 + 31553783 = 31553794
17 + 31553777 = 31553794
131 + 31553663 = 31553794
443 + 31553351 = 31553794
521 + 31553273 = 31553794
593 + 31553201 = 31553794
617 + 31553177 = 31553794
773 + 31553021 = 31553794

Showing the first eight; more decompositions exist.
