Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72492, here are decompositions:
- 11 + 72481 = 72492
- 23 + 72469 = 72492
- 31 + 72461 = 72492
- 61 + 72431 = 72492
- 71 + 72421 = 72492
- 109 + 72383 = 72492
- 113 + 72379 = 72492
- 139 + 72353 = 72492
Showing the first eight; more decompositions exist.
