Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47138, here are decompositions:
- 19 + 47119 = 47138
- 79 + 47059 = 47138
- 97 + 47041 = 47138
- 181 + 46957 = 47138
- 271 + 46867 = 47138
- 277 + 46861 = 47138
- 307 + 46831 = 47138
- 331 + 46807 = 47138
Showing the first eight; more decompositions exist.
