Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142694, here are decompositions:
- 37 + 142657 = 142694
- 103 + 142591 = 142694
- 127 + 142567 = 142694
- 151 + 142543 = 142694
- 157 + 142537 = 142694
- 193 + 142501 = 142694
- 241 + 142453 = 142694
- 313 + 142381 = 142694
Showing the first eight; more decompositions exist.
