Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71992, here are decompositions:
- 5 + 71987 = 71992
- 29 + 71963 = 71992
- 59 + 71933 = 71992
- 83 + 71909 = 71992
- 113 + 71879 = 71992
- 131 + 71861 = 71992
- 149 + 71843 = 71992
- 251 + 71741 = 71992
Showing the first eight; more decompositions exist.
