Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 704, here are decompositions:
- 3 + 701 = 704
- 13 + 691 = 704
- 31 + 673 = 704
- 43 + 661 = 704
- 61 + 643 = 704
- 73 + 631 = 704
- 97 + 607 = 704
- 103 + 601 = 704
Showing the first eight; more decompositions exist.
