Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149998, here are decompositions:
- 5 + 149993 = 149998
- 29 + 149969 = 149998
- 59 + 149939 = 149998
- 89 + 149909 = 149998
- 131 + 149867 = 149998
- 137 + 149861 = 149998
- 227 + 149771 = 149998
- 239 + 149759 = 149998
Showing the first eight; more decompositions exist.
