Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127836, here are decompositions:
- 17 + 127819 = 127836
- 19 + 127817 = 127836
- 29 + 127807 = 127836
- 73 + 127763 = 127836
- 89 + 127747 = 127836
- 97 + 127739 = 127836
- 103 + 127733 = 127836
- 109 + 127727 = 127836
Showing the first eight; more decompositions exist.
