Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742554, here are decompositions:

3 + 8742551 = 8742554
13 + 8742541 = 8742554
43 + 8742511 = 8742554
61 + 8742493 = 8742554
241 + 8742313 = 8742554
367 + 8742187 = 8742554
397 + 8742157 = 8742554
421 + 8742133 = 8742554

Showing the first eight; more decompositions exist.
