Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142708, here are decompositions:
- 11 + 142697 = 142708
- 89 + 142619 = 142708
- 101 + 142607 = 142708
- 107 + 142601 = 142708
- 149 + 142559 = 142708
- 179 + 142529 = 142708
- 239 + 142469 = 142708
- 281 + 142427 = 142708
Showing the first eight; more decompositions exist.
