Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130648, here are decompositions:
- 5 + 130643 = 130648
- 17 + 130631 = 130648
- 29 + 130619 = 130648
- 59 + 130589 = 130648
- 101 + 130547 = 130648
- 131 + 130517 = 130648
- 179 + 130469 = 130648
- 191 + 130457 = 130648
Showing the first eight; more decompositions exist.
