Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149782, here are decompositions:
- 11 + 149771 = 149782
- 23 + 149759 = 149782
- 53 + 149729 = 149782
- 71 + 149711 = 149782
- 179 + 149603 = 149782
- 239 + 149543 = 149782
- 251 + 149531 = 149782
- 263 + 149519 = 149782
Showing the first eight; more decompositions exist.
