Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717400, here are decompositions:
- 7 + 8717393 = 8717400
- 11 + 8717389 = 8717400
- 47 + 8717353 = 8717400
- 59 + 8717341 = 8717400
- 71 + 8717329 = 8717400
- 113 + 8717287 = 8717400
- 127 + 8717273 = 8717400
- 137 + 8717263 = 8717400
Showing the first eight; more decompositions exist.
