Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27956, here are decompositions:
- 3 + 27953 = 27956
- 13 + 27943 = 27956
- 37 + 27919 = 27956
- 73 + 27883 = 27956
- 109 + 27847 = 27956
- 139 + 27817 = 27956
- 157 + 27799 = 27956
- 163 + 27793 = 27956
Showing the first eight; more decompositions exist.
