Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742854, here are decompositions:

7 + 8742847 = 8742854
37 + 8742817 = 8742854
67 + 8742787 = 8742854
181 + 8742673 = 8742854
277 + 8742577 = 8742854
283 + 8742571 = 8742854
313 + 8742541 = 8742854
433 + 8742421 = 8742854

Showing the first eight; more decompositions exist.
