Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27890, here are decompositions:
- 7 + 27883 = 27890
- 43 + 27847 = 27890
- 67 + 27823 = 27890
- 73 + 27817 = 27890
- 97 + 27793 = 27890
- 127 + 27763 = 27890
- 139 + 27751 = 27890
- 151 + 27739 = 27890
Showing the first eight; more decompositions exist.
