Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553702, here are decompositions:

31 + 31553671 = 31553702
43 + 31553659 = 31553702
199 + 31553503 = 31553702
541 + 31553161 = 31553702
613 + 31553089 = 31553702
811 + 31552891 = 31553702
823 + 31552879 = 31553702
1009 + 31552693 = 31553702

Showing the first eight; more decompositions exist.
