Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691004, here are decompositions:

41 + 8690963 = 8691004
53 + 8690951 = 8691004
83 + 8690921 = 8691004
137 + 8690867 = 8691004
191 + 8690813 = 8691004
263 + 8690741 = 8691004
401 + 8690603 = 8691004
593 + 8690411 = 8691004

Showing the first eight; more decompositions exist.
