Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742998, here are decompositions:

67 + 8742931 = 8742998
79 + 8742919 = 8742998
151 + 8742847 = 8742998
181 + 8742817 = 8742998
211 + 8742787 = 8742998
421 + 8742577 = 8742998
457 + 8742541 = 8742998
487 + 8742511 = 8742998

Showing the first eight; more decompositions exist.
