Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72970, here are decompositions:
- 11 + 72959 = 72970
- 17 + 72953 = 72970
- 47 + 72923 = 72970
- 59 + 72911 = 72970
- 101 + 72869 = 72970
- 173 + 72797 = 72970
- 251 + 72719 = 72970
- 263 + 72707 = 72970
Showing the first eight; more decompositions exist.
