Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64878, here are decompositions:
- 7 + 64871 = 64878
- 29 + 64849 = 64878
- 61 + 64817 = 64878
- 67 + 64811 = 64878
- 97 + 64781 = 64878
- 131 + 64747 = 64878
- 199 + 64679 = 64878
- 211 + 64667 = 64878
Showing the first eight; more decompositions exist.
