Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552274, here are decompositions:

3 + 31552271 = 31552274
37 + 31552237 = 31552274
67 + 31552207 = 31552274
241 + 31552033 = 31552274
277 + 31551997 = 31552274
337 + 31551937 = 31552274
373 + 31551901 = 31552274
421 + 31551853 = 31552274

Showing the first eight; more decompositions exist.
