Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670040, here are decompositions:

3 + 8670037 = 8670040
11 + 8670029 = 8670040
47 + 8669993 = 8670040
59 + 8669981 = 8670040
101 + 8669939 = 8670040
179 + 8669861 = 8670040
263 + 8669777 = 8670040
383 + 8669657 = 8670040

Showing the first eight; more decompositions exist.
