Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487278, here are decompositions:
- 17 + 487261 = 487278
- 31 + 487247 = 487278
- 59 + 487219 = 487278
- 67 + 487211 = 487278
- 101 + 487177 = 487278
- 167 + 487111 = 487278
- 179 + 487099 = 487278
- 199 + 487079 = 487278
Showing the first eight; more decompositions exist.
