Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 48642, here are decompositions:
- 19 + 48623 = 48642
- 23 + 48619 = 48642
- 31 + 48611 = 48642
- 53 + 48589 = 48642
- 71 + 48571 = 48642
- 79 + 48563 = 48642
- 101 + 48541 = 48642
- 103 + 48539 = 48642
Showing the first eight; more decompositions exist.
