Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739142, here are decompositions:

23 + 8739119 = 8739142
29 + 8739113 = 8739142
89 + 8739053 = 8739142
179 + 8738963 = 8739142
359 + 8738783 = 8739142
383 + 8738759 = 8739142
431 + 8738711 = 8739142
563 + 8738579 = 8739142

Showing the first eight; more decompositions exist.
