Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7698, here are decompositions:
- 7 + 7691 = 7698
- 11 + 7687 = 7698
- 17 + 7681 = 7698
- 29 + 7669 = 7698
- 59 + 7639 = 7698
- 107 + 7591 = 7698
- 109 + 7589 = 7698
- 137 + 7561 = 7698
Showing the first eight; more decompositions exist.
