Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72260, here are decompositions:
- 7 + 72253 = 72260
- 31 + 72229 = 72260
- 37 + 72223 = 72260
- 151 + 72109 = 72260
- 157 + 72103 = 72260
- 229 + 72031 = 72260
- 241 + 72019 = 72260
- 277 + 71983 = 72260
Showing the first eight; more decompositions exist.
