Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561738, here are decompositions:

5 + 561733 = 561738
71 + 561667 = 561738
131 + 561607 = 561738
139 + 561599 = 561738
179 + 561559 = 561738
277 + 561461 = 561738
349 + 561389 = 561738
379 + 561359 = 561738

Showing the first eight; more decompositions exist.
