Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81046, here are decompositions:
- 3 + 81043 = 81046
- 5 + 81041 = 81046
- 23 + 81023 = 81046
- 29 + 81017 = 81046
- 83 + 80963 = 81046
- 113 + 80933 = 81046
- 137 + 80909 = 81046
- 149 + 80897 = 81046
Showing the first eight; more decompositions exist.
