Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488280, here are decompositions:
- 17 + 488263 = 488280
- 19 + 488261 = 488280
- 31 + 488249 = 488280
- 41 + 488239 = 488280
- 47 + 488233 = 488280
- 53 + 488227 = 488280
- 71 + 488209 = 488280
- 73 + 488207 = 488280
Showing the first eight; more decompositions exist.
