Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553834, here are decompositions:

31 + 31553803 = 31553834
73 + 31553761 = 31553834
127 + 31553707 = 31553834
163 + 31553671 = 31553834
307 + 31553527 = 31553834
331 + 31553503 = 31553834
601 + 31553233 = 31553834
673 + 31553161 = 31553834

Showing the first eight; more decompositions exist.
