Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149818, here are decompositions:
- 47 + 149771 = 149818
- 59 + 149759 = 149818
- 89 + 149729 = 149818
- 101 + 149717 = 149818
- 107 + 149711 = 149818
- 191 + 149627 = 149818
- 239 + 149579 = 149818
- 257 + 149561 = 149818
Showing the first eight; more decompositions exist.
