Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136972, here are decompositions:
- 23 + 136949 = 136972
- 29 + 136943 = 136972
- 83 + 136889 = 136972
- 89 + 136883 = 136972
- 113 + 136859 = 136972
- 131 + 136841 = 136972
- 233 + 136739 = 136972
- 239 + 136733 = 136972
Showing the first eight; more decompositions exist.
