Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136920, here are decompositions:
- 23 + 136897 = 136920
- 31 + 136889 = 136920
- 37 + 136883 = 136920
- 41 + 136879 = 136920
- 59 + 136861 = 136920
- 61 + 136859 = 136920
- 71 + 136849 = 136920
- 79 + 136841 = 136920
Showing the first eight; more decompositions exist.
