Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78912, here are decompositions:
- 11 + 78901 = 78912
- 19 + 78893 = 78912
- 23 + 78889 = 78912
- 59 + 78853 = 78912
- 73 + 78839 = 78912
- 89 + 78823 = 78912
- 103 + 78809 = 78912
- 109 + 78803 = 78912
Showing the first eight; more decompositions exist.
