Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72056, here are decompositions:
- 3 + 72053 = 72056
- 13 + 72043 = 72056
- 37 + 72019 = 72056
- 73 + 71983 = 72056
- 109 + 71947 = 72056
- 139 + 71917 = 72056
- 157 + 71899 = 72056
- 337 + 71719 = 72056
Showing the first eight; more decompositions exist.
