Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149548, here are decompositions:
- 5 + 149543 = 149548
- 17 + 149531 = 149548
- 29 + 149519 = 149548
- 59 + 149489 = 149548
- 89 + 149459 = 149548
- 107 + 149441 = 149548
- 131 + 149417 = 149548
- 137 + 149411 = 149548
Showing the first eight; more decompositions exist.
