Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142426, here are decompositions:
- 5 + 142421 = 142426
- 23 + 142403 = 142426
- 107 + 142319 = 142426
- 233 + 142193 = 142426
- 257 + 142169 = 142426
- 269 + 142157 = 142426
- 359 + 142067 = 142426
- 419 + 142007 = 142426
Showing the first eight; more decompositions exist.
