Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161352, here are decompositions:
- 11 + 161341 = 161352
- 13 + 161339 = 161352
- 19 + 161333 = 161352
- 29 + 161323 = 161352
- 43 + 161309 = 161352
- 71 + 161281 = 161352
- 89 + 161263 = 161352
- 131 + 161221 = 161352
Showing the first eight; more decompositions exist.
