Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70128, here are decompositions:
- 5 + 70123 = 70128
- 7 + 70121 = 70128
- 11 + 70117 = 70128
- 17 + 70111 = 70128
- 29 + 70099 = 70128
- 61 + 70067 = 70128
- 67 + 70061 = 70128
- 89 + 70039 = 70128
Showing the first eight; more decompositions exist.
