Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84878, here are decompositions:
- 7 + 84871 = 84878
- 19 + 84859 = 84878
- 67 + 84811 = 84878
- 127 + 84751 = 84878
- 181 + 84697 = 84878
- 229 + 84649 = 84878
- 379 + 84499 = 84878
- 397 + 84481 = 84878
Showing the first eight; more decompositions exist.
