Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690782, here are decompositions:

41 + 8690741 = 8690782
179 + 8690603 = 8690782
251 + 8690531 = 8690782
293 + 8690489 = 8690782
383 + 8690399 = 8690782
431 + 8690351 = 8690782
449 + 8690333 = 8690782
479 + 8690303 = 8690782

Showing the first eight; more decompositions exist.
