Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72308, here are decompositions:
- 31 + 72277 = 72308
- 37 + 72271 = 72308
- 79 + 72229 = 72308
- 97 + 72211 = 72308
- 139 + 72169 = 72308
- 199 + 72109 = 72308
- 277 + 72031 = 72308
- 337 + 71971 = 72308
Showing the first eight; more decompositions exist.
