Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156998, here are decompositions:
- 19 + 156979 = 156998
- 31 + 156967 = 156998
- 97 + 156901 = 156998
- 157 + 156841 = 156998
- 181 + 156817 = 156998
- 199 + 156799 = 156998
- 271 + 156727 = 156998
- 307 + 156691 = 156998
Showing the first eight; more decompositions exist.
