Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561372, here are decompositions:

5 + 561367 = 561372
13 + 561359 = 561372
29 + 561343 = 561372
59 + 561313 = 561372
173 + 561199 = 561372
181 + 561191 = 561372
191 + 561181 = 561372
199 + 561173 = 561372

Showing the first eight; more decompositions exist.
