Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142348, here are decompositions:
- 29 + 142319 = 142348
- 131 + 142217 = 142348
- 137 + 142211 = 142348
- 179 + 142169 = 142348
- 191 + 142157 = 142348
- 197 + 142151 = 142348
- 251 + 142097 = 142348
- 281 + 142067 = 142348
Showing the first eight; more decompositions exist.
