Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553606, here are decompositions:

79 + 31553527 = 31553606
103 + 31553503 = 31553606
223 + 31553383 = 31553606
373 + 31553233 = 31553606
607 + 31552999 = 31553606
727 + 31552879 = 31553606
859 + 31552747 = 31553606
967 + 31552639 = 31553606

Showing the first eight; more decompositions exist.
