Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553006, here are decompositions:

7 + 31552999 = 31553006
127 + 31552879 = 31553006
313 + 31552693 = 31553006
367 + 31552639 = 31553006
577 + 31552429 = 31553006
613 + 31552393 = 31553006
619 + 31552387 = 31553006
769 + 31552237 = 31553006

Showing the first eight; more decompositions exist.
