Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172434, here are decompositions:
- 7 + 172427 = 172434
- 11 + 172423 = 172434
- 13 + 172421 = 172434
- 23 + 172411 = 172434
- 61 + 172373 = 172434
- 83 + 172351 = 172434
- 103 + 172331 = 172434
- 113 + 172321 = 172434
Showing the first eight; more decompositions exist.
