Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675890, here are decompositions:

11 + 8675879 = 8675890
29 + 8675861 = 8675890
191 + 8675699 = 8675890
239 + 8675651 = 8675890
269 + 8675621 = 8675890
317 + 8675573 = 8675890
449 + 8675441 = 8675890
491 + 8675399 = 8675890

Showing the first eight; more decompositions exist.
