Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6504, here are decompositions:
- 13 + 6491 = 6504
- 23 + 6481 = 6504
- 31 + 6473 = 6504
- 53 + 6451 = 6504
- 83 + 6421 = 6504
- 107 + 6397 = 6504
- 131 + 6373 = 6504
- 137 + 6367 = 6504
Showing the first eight; more decompositions exist.
