Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553426, here are decompositions:

43 + 31553383 = 31553426
67 + 31553359 = 31553426
193 + 31553233 = 31553426
337 + 31553089 = 31553426
349 + 31553077 = 31553426
409 + 31553017 = 31553426
547 + 31552879 = 31553426
733 + 31552693 = 31553426

Showing the first eight; more decompositions exist.
