Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81476, here are decompositions:
- 13 + 81463 = 81476
- 19 + 81457 = 81476
- 37 + 81439 = 81476
- 67 + 81409 = 81476
- 103 + 81373 = 81476
- 127 + 81349 = 81476
- 193 + 81283 = 81476
- 277 + 81199 = 81476
Showing the first eight; more decompositions exist.
