Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72486, here are decompositions:
- 5 + 72481 = 72486
- 17 + 72469 = 72486
- 19 + 72467 = 72486
- 103 + 72383 = 72486
- 107 + 72379 = 72486
- 149 + 72337 = 72486
- 173 + 72313 = 72486
- 179 + 72307 = 72486
Showing the first eight; more decompositions exist.
