Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6578, here are decompositions:
- 7 + 6571 = 6578
- 31 + 6547 = 6578
- 97 + 6481 = 6578
- 109 + 6469 = 6578
- 127 + 6451 = 6578
- 151 + 6427 = 6578
- 157 + 6421 = 6578
- 181 + 6397 = 6578
Showing the first eight; more decompositions exist.
