Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553894, here are decompositions:

61 + 31553833 = 31553894
223 + 31553671 = 31553894
277 + 31553617 = 31553894
367 + 31553527 = 31553894
661 + 31553233 = 31553894
733 + 31553161 = 31553894
877 + 31553017 = 31553894
1063 + 31552831 = 31553894

Showing the first eight; more decompositions exist.
