Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561950, here are decompositions:

3 + 561947 = 561950
7 + 561943 = 561950
19 + 561931 = 561950
43 + 561907 = 561950
163 + 561787 = 561950
283 + 561667 = 561950
397 + 561553 = 561950
421 + 561529 = 561950

Showing the first eight; more decompositions exist.
