Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87648, here are decompositions:
- 5 + 87643 = 87648
- 7 + 87641 = 87648
- 17 + 87631 = 87648
- 19 + 87629 = 87648
- 59 + 87589 = 87648
- 61 + 87587 = 87648
- 89 + 87559 = 87648
- 101 + 87547 = 87648
Showing the first eight; more decompositions exist.
