Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691788, here are decompositions:

37 + 8691751 = 8691788
199 + 8691589 = 8691788
307 + 8691481 = 8691788
337 + 8691451 = 8691788
397 + 8691391 = 8691788
421 + 8691367 = 8691788
541 + 8691247 = 8691788
577 + 8691211 = 8691788

Showing the first eight; more decompositions exist.
