Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488, here are decompositions:
- 31 + 457 = 488
- 67 + 421 = 488
- 79 + 409 = 488
- 109 + 379 = 488
- 139 + 349 = 488
- 151 + 337 = 488
- 157 + 331 = 488
- 181 + 307 = 488
Showing the first eight; more decompositions exist.
