Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691244, here are decompositions:

5 + 8691239 = 8691244
281 + 8690963 = 8691244
293 + 8690951 = 8691244
431 + 8690813 = 8691244
461 + 8690783 = 8691244
503 + 8690741 = 8691244
641 + 8690603 = 8691244
677 + 8690567 = 8691244

Showing the first eight; more decompositions exist.
