Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72502, here are decompositions:
- 5 + 72497 = 72502
- 41 + 72461 = 72502
- 71 + 72431 = 72502
- 149 + 72353 = 72502
- 233 + 72269 = 72502
- 251 + 72251 = 72502
- 281 + 72221 = 72502
- 401 + 72101 = 72502
Showing the first eight; more decompositions exist.
