Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149842, here are decompositions:
- 3 + 149839 = 149842
- 5 + 149837 = 149842
- 71 + 149771 = 149842
- 83 + 149759 = 149842
- 113 + 149729 = 149842
- 131 + 149711 = 149842
- 239 + 149603 = 149842
- 263 + 149579 = 149842
Showing the first eight; more decompositions exist.
