Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553706, here are decompositions:

43 + 31553663 = 31553706
47 + 31553659 = 31553706
89 + 31553617 = 31553706
97 + 31553609 = 31553706
179 + 31553527 = 31553706
337 + 31553369 = 31553706
347 + 31553359 = 31553706
367 + 31553339 = 31553706

Showing the first eight; more decompositions exist.
