Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553582, here are decompositions:

79 + 31553503 = 31553582
199 + 31553383 = 31553582
223 + 31553359 = 31553582
349 + 31553233 = 31553582
421 + 31553161 = 31553582
691 + 31552891 = 31553582
751 + 31552831 = 31553582
1093 + 31552489 = 31553582

Showing the first eight; more decompositions exist.
