Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561884, here are decompositions:

97 + 561787 = 561884
151 + 561733 = 561884
181 + 561703 = 561884
277 + 561607 = 561884
331 + 561553 = 561884
541 + 561343 = 561884
571 + 561313 = 561884
577 + 561307 = 561884

Showing the first eight; more decompositions exist.
