Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720082, here are decompositions:
- 11 + 8720071 = 8720082
- 83 + 8719999 = 8720082
- 131 + 8719951 = 8720082
- 139 + 8719943 = 8720082
- 179 + 8719903 = 8720082
- 251 + 8719831 = 8720082
- 263 + 8719819 = 8720082
- 269 + 8719813 = 8720082
Showing the first eight; more decompositions exist.
