Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6488, here are decompositions:
- 7 + 6481 = 6488
- 19 + 6469 = 6488
- 37 + 6451 = 6488
- 61 + 6427 = 6488
- 67 + 6421 = 6488
- 109 + 6379 = 6488
- 127 + 6361 = 6488
- 151 + 6337 = 6488
Showing the first eight; more decompositions exist.
