Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553174, here are decompositions:

13 + 31553161 = 31553174
97 + 31553077 = 31553174
157 + 31553017 = 31553174
283 + 31552891 = 31553174
571 + 31552603 = 31553174
787 + 31552387 = 31553174
823 + 31552351 = 31553174
937 + 31552237 = 31553174

Showing the first eight; more decompositions exist.
