Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149798, here are decompositions:
- 7 + 149791 = 149798
- 31 + 149767 = 149798
- 67 + 149731 = 149798
- 109 + 149689 = 149798
- 277 + 149521 = 149798
- 307 + 149491 = 149798
- 379 + 149419 = 149798
- 421 + 149377 = 149798
Showing the first eight; more decompositions exist.
