Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691800, here are decompositions:

37 + 8691763 = 8691800
67 + 8691733 = 8691800
127 + 8691673 = 8691800
157 + 8691643 = 8691800
211 + 8691589 = 8691800
331 + 8691469 = 8691800
349 + 8691451 = 8691800
367 + 8691433 = 8691800

Showing the first eight; more decompositions exist.
