Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561362, here are decompositions:

3 + 561359 = 561362
19 + 561343 = 561362
163 + 561199 = 561362
181 + 561181 = 561362
271 + 561091 = 561362
283 + 561079 = 561362
421 + 560941 = 561362
433 + 560929 = 561362

Showing the first eight; more decompositions exist.
