Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553258, here are decompositions:

97 + 31553161 = 31553258
181 + 31553077 = 31553258
241 + 31553017 = 31553258
367 + 31552891 = 31553258
379 + 31552879 = 31553258
577 + 31552681 = 31553258
619 + 31552639 = 31553258
769 + 31552489 = 31553258

Showing the first eight; more decompositions exist.
