Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672742, here are decompositions:

11 + 8672731 = 8672742
19 + 8672723 = 8672742
83 + 8672659 = 8672742
101 + 8672641 = 8672742
103 + 8672639 = 8672742
179 + 8672563 = 8672742
181 + 8672561 = 8672742
191 + 8672551 = 8672742

Showing the first eight; more decompositions exist.
