Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676890, here are decompositions:

7 + 8676883 = 8676890
43 + 8676847 = 8676890
109 + 8676781 = 8676890
139 + 8676751 = 8676890
199 + 8676691 = 8676890
349 + 8676541 = 8676890
373 + 8676517 = 8676890
571 + 8676319 = 8676890

Showing the first eight; more decompositions exist.
