Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72940, here are decompositions:
- 3 + 72937 = 72940
- 17 + 72923 = 72940
- 29 + 72911 = 72940
- 47 + 72893 = 72940
- 71 + 72869 = 72940
- 173 + 72767 = 72940
- 233 + 72707 = 72940
- 239 + 72701 = 72940
Showing the first eight; more decompositions exist.
