Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739904, here are decompositions:

3 + 8739901 = 8739904
53 + 8739851 = 8739904
83 + 8739821 = 8739904
101 + 8739803 = 8739904
137 + 8739767 = 8739904
191 + 8739713 = 8739904
233 + 8739671 = 8739904
281 + 8739623 = 8739904

Showing the first eight; more decompositions exist.
