Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7486, here are decompositions:
- 5 + 7481 = 7486
- 29 + 7457 = 7486
- 53 + 7433 = 7486
- 137 + 7349 = 7486
- 179 + 7307 = 7486
- 233 + 7253 = 7486
- 239 + 7247 = 7486
- 257 + 7229 = 7486
Showing the first eight; more decompositions exist.
