Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72526, here are decompositions:
- 23 + 72503 = 72526
- 29 + 72497 = 72526
- 59 + 72467 = 72526
- 173 + 72353 = 72526
- 239 + 72287 = 72526
- 257 + 72269 = 72526
- 353 + 72173 = 72526
- 359 + 72167 = 72526
Showing the first eight; more decompositions exist.
