Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70272, here are decompositions:
- 23 + 70249 = 70272
- 31 + 70241 = 70272
- 43 + 70229 = 70272
- 71 + 70201 = 70272
- 73 + 70199 = 70272
- 89 + 70183 = 70272
- 109 + 70163 = 70272
- 131 + 70141 = 70272
Showing the first eight; more decompositions exist.
