Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72498, here are decompositions:
- 5 + 72493 = 72498
- 17 + 72481 = 72498
- 29 + 72469 = 72498
- 31 + 72467 = 72498
- 37 + 72461 = 72498
- 67 + 72431 = 72498
- 131 + 72367 = 72498
- 157 + 72341 = 72498
Showing the first eight; more decompositions exist.
