Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72022, here are decompositions:
- 3 + 72019 = 72022
- 23 + 71999 = 72022
- 29 + 71993 = 72022
- 59 + 71963 = 72022
- 89 + 71933 = 72022
- 113 + 71909 = 72022
- 173 + 71849 = 72022
- 179 + 71843 = 72022
Showing the first eight; more decompositions exist.
