Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557642, here are decompositions:

3 + 557639 = 557642
31 + 557611 = 557642
109 + 557533 = 557642
181 + 557461 = 557642
193 + 557449 = 557642
199 + 557443 = 557642
271 + 557371 = 557642
313 + 557329 = 557642

Showing the first eight; more decompositions exist.
