Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553884, here are decompositions:

17 + 31553867 = 31553884
83 + 31553801 = 31553884
101 + 31553783 = 31553884
107 + 31553777 = 31553884
431 + 31553453 = 31553884
563 + 31553321 = 31553884
683 + 31553201 = 31553884
701 + 31553183 = 31553884

Showing the first eight; more decompositions exist.
