Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142718, here are decompositions:
- 7 + 142711 = 142718
- 19 + 142699 = 142718
- 61 + 142657 = 142718
- 109 + 142609 = 142718
- 127 + 142591 = 142718
- 151 + 142567 = 142718
- 181 + 142537 = 142718
- 337 + 142381 = 142718
Showing the first eight; more decompositions exist.
