Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30936, here are decompositions:
- 5 + 30931 = 30936
- 43 + 30893 = 30936
- 67 + 30869 = 30936
- 83 + 30853 = 30936
- 97 + 30839 = 30936
- 107 + 30829 = 30936
- 127 + 30809 = 30936
- 163 + 30773 = 30936
Showing the first eight; more decompositions exist.
