Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147988, here are decompositions:
- 11 + 147977 = 147988
- 107 + 147881 = 147988
- 227 + 147761 = 147988
- 317 + 147671 = 147988
- 359 + 147629 = 147988
- 431 + 147557 = 147988
- 569 + 147419 = 147988
- 587 + 147401 = 147988
Showing the first eight; more decompositions exist.
