Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170228, here are decompositions:
- 31 + 170197 = 170228
- 61 + 170167 = 170228
- 127 + 170101 = 170228
- 181 + 170047 = 170228
- 199 + 170029 = 170228
- 241 + 169987 = 170228
- 271 + 169957 = 170228
- 277 + 169951 = 170228
Showing the first eight; more decompositions exist.
