Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460558, here are decompositions:

7 + 31460551 = 31460558
61 + 31460497 = 31460558
67 + 31460491 = 31460558
127 + 31460431 = 31460558
211 + 31460347 = 31460558
229 + 31460329 = 31460558
277 + 31460281 = 31460558
421 + 31460137 = 31460558

Showing the first eight; more decompositions exist.
