Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40748, here are decompositions:
- 109 + 40639 = 40748
- 139 + 40609 = 40748
- 151 + 40597 = 40748
- 157 + 40591 = 40748
- 229 + 40519 = 40748
- 241 + 40507 = 40748
- 277 + 40471 = 40748
- 397 + 40351 = 40748
Showing the first eight; more decompositions exist.
