Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71908, here are decompositions:
- 29 + 71879 = 71908
- 41 + 71867 = 71908
- 47 + 71861 = 71908
- 59 + 71849 = 71908
- 71 + 71837 = 71908
- 101 + 71807 = 71908
- 131 + 71777 = 71908
- 167 + 71741 = 71908
Showing the first eight; more decompositions exist.
