Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72546, here are decompositions:
- 13 + 72533 = 72546
- 43 + 72503 = 72546
- 53 + 72493 = 72546
- 79 + 72467 = 72546
- 163 + 72383 = 72546
- 167 + 72379 = 72546
- 179 + 72367 = 72546
- 193 + 72353 = 72546
Showing the first eight; more decompositions exist.
