Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672806, here are decompositions:

5 + 8672801 = 8672806
17 + 8672789 = 8672806
83 + 8672723 = 8672806
167 + 8672639 = 8672806
293 + 8672513 = 8672806
383 + 8672423 = 8672806
419 + 8672387 = 8672806
509 + 8672297 = 8672806

Showing the first eight; more decompositions exist.
