Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6522, here are decompositions:
- 31 + 6491 = 6522
- 41 + 6481 = 6522
- 53 + 6469 = 6522
- 71 + 6451 = 6522
- 73 + 6449 = 6522
- 101 + 6421 = 6522
- 149 + 6373 = 6522
- 163 + 6359 = 6522
Showing the first eight; more decompositions exist.
