Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72434, here are decompositions:
- 3 + 72431 = 72434
- 13 + 72421 = 72434
- 67 + 72367 = 72434
- 97 + 72337 = 72434
- 127 + 72307 = 72434
- 157 + 72277 = 72434
- 163 + 72271 = 72434
- 181 + 72253 = 72434
Showing the first eight; more decompositions exist.
