Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561942, here are decompositions:

11 + 561931 = 561942
19 + 561923 = 561942
103 + 561839 = 561942
113 + 561829 = 561942
181 + 561761 = 561942
229 + 561713 = 561942
239 + 561703 = 561942
383 + 561559 = 561942

Showing the first eight; more decompositions exist.
