Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553084, here are decompositions:

7 + 31553077 = 31553084
67 + 31553017 = 31553084
193 + 31552891 = 31553084
337 + 31552747 = 31553084
463 + 31552621 = 31553084
547 + 31552537 = 31553084
691 + 31552393 = 31553084
733 + 31552351 = 31553084

Showing the first eight; more decompositions exist.
