Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7748, here are decompositions:
- 7 + 7741 = 7748
- 31 + 7717 = 7748
- 61 + 7687 = 7748
- 67 + 7681 = 7748
- 79 + 7669 = 7748
- 109 + 7639 = 7748
- 127 + 7621 = 7748
- 157 + 7591 = 7748
Showing the first eight; more decompositions exist.
