Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82972, here are decompositions:
- 59 + 82913 = 82972
- 83 + 82889 = 82972
- 89 + 82883 = 82972
- 173 + 82799 = 82972
- 179 + 82793 = 82972
- 191 + 82781 = 82972
- 251 + 82721 = 82972
- 353 + 82619 = 82972
Showing the first eight; more decompositions exist.
