Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72548, here are decompositions:
- 67 + 72481 = 72548
- 79 + 72469 = 72548
- 127 + 72421 = 72548
- 181 + 72367 = 72548
- 211 + 72337 = 72548
- 241 + 72307 = 72548
- 271 + 72277 = 72548
- 277 + 72271 = 72548
Showing the first eight; more decompositions exist.
