Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81062, here are decompositions:
- 13 + 81049 = 81062
- 19 + 81043 = 81062
- 31 + 81031 = 81062
- 43 + 81019 = 81062
- 61 + 81001 = 81062
- 73 + 80989 = 81062
- 109 + 80953 = 81062
- 139 + 80923 = 81062
Showing the first eight; more decompositions exist.
