Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553060, here are decompositions:

43 + 31553017 = 31553060
61 + 31552999 = 31553060
181 + 31552879 = 31553060
229 + 31552831 = 31553060
313 + 31552747 = 31553060
367 + 31552693 = 31553060
379 + 31552681 = 31553060
421 + 31552639 = 31553060

Showing the first eight; more decompositions exist.
