Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761842, here are decompositions:

53 + 8761789 = 8761842
79 + 8761763 = 8761842
109 + 8761733 = 8761842
139 + 8761703 = 8761842
151 + 8761691 = 8761842
211 + 8761631 = 8761842
223 + 8761619 = 8761842
241 + 8761601 = 8761842

Showing the first eight; more decompositions exist.
