Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7718, here are decompositions:
- 19 + 7699 = 7718
- 31 + 7687 = 7718
- 37 + 7681 = 7718
- 79 + 7639 = 7718
- 97 + 7621 = 7718
- 127 + 7591 = 7718
- 157 + 7561 = 7718
- 181 + 7537 = 7718
Showing the first eight; more decompositions exist.
