Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72248, here are decompositions:
- 19 + 72229 = 72248
- 37 + 72211 = 72248
- 79 + 72169 = 72248
- 109 + 72139 = 72248
- 139 + 72109 = 72248
- 157 + 72091 = 72248
- 229 + 72019 = 72248
- 277 + 71971 = 72248
Showing the first eight; more decompositions exist.
