Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157222, here are decompositions:
- 3 + 157219 = 157222
- 5 + 157217 = 157222
- 11 + 157211 = 157222
- 41 + 157181 = 157222
- 59 + 157163 = 157222
- 89 + 157133 = 157222
- 113 + 157109 = 157222
- 173 + 157049 = 157222
Showing the first eight; more decompositions exist.
