Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552958, here are decompositions:

67 + 31552891 = 31552958
79 + 31552879 = 31552958
127 + 31552831 = 31552958
211 + 31552747 = 31552958
277 + 31552681 = 31552958
337 + 31552621 = 31552958
379 + 31552579 = 31552958
421 + 31552537 = 31552958

Showing the first eight; more decompositions exist.
