Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72098, here are decompositions:
- 7 + 72091 = 72098
- 67 + 72031 = 72098
- 79 + 72019 = 72098
- 127 + 71971 = 72098
- 151 + 71947 = 72098
- 157 + 71941 = 72098
- 181 + 71917 = 72098
- 199 + 71899 = 72098
Showing the first eight; more decompositions exist.
