Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648890, here are decompositions:

11 + 8648879 = 8648890
23 + 8648867 = 8648890
53 + 8648837 = 8648890
59 + 8648831 = 8648890
149 + 8648741 = 8648890
347 + 8648543 = 8648890
353 + 8648537 = 8648890
359 + 8648531 = 8648890

Showing the first eight; more decompositions exist.
