Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149830, here are decompositions:
- 3 + 149827 = 149830
- 59 + 149771 = 149830
- 71 + 149759 = 149830
- 101 + 149729 = 149830
- 113 + 149717 = 149830
- 227 + 149603 = 149830
- 251 + 149579 = 149830
- 269 + 149561 = 149830
Showing the first eight; more decompositions exist.
