Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677142, here are decompositions:

3 + 8677139 = 8677142
151 + 8676991 = 8677142
193 + 8676949 = 8677142
373 + 8676769 = 8677142
421 + 8676721 = 8677142
499 + 8676643 = 8677142
541 + 8676601 = 8677142
601 + 8676541 = 8677142

Showing the first eight; more decompositions exist.
