Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149446, here are decompositions:
- 5 + 149441 = 149446
- 23 + 149423 = 149446
- 29 + 149417 = 149446
- 47 + 149399 = 149446
- 53 + 149393 = 149446
- 113 + 149333 = 149446
- 137 + 149309 = 149446
- 149 + 149297 = 149446
Showing the first eight; more decompositions exist.
