Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029878, here are decompositions:
- 19 + 1029859 = 1029878
- 37 + 1029841 = 1029878
- 127 + 1029751 = 1029878
- 181 + 1029697 = 1029878
- 277 + 1029601 = 1029878
- 331 + 1029547 = 1029878
- 379 + 1029499 = 1029878
- 397 + 1029481 = 1029878
Showing the first eight; more decompositions exist.
