Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172524, here are decompositions:
- 5 + 172519 = 172524
- 7 + 172517 = 172524
- 17 + 172507 = 172524
- 83 + 172441 = 172524
- 97 + 172427 = 172524
- 101 + 172423 = 172524
- 103 + 172421 = 172524
- 113 + 172411 = 172524
Showing the first eight; more decompositions exist.
