Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86390, here are decompositions:
- 19 + 86371 = 86390
- 37 + 86353 = 86390
- 67 + 86323 = 86390
- 79 + 86311 = 86390
- 97 + 86293 = 86390
- 103 + 86287 = 86390
- 127 + 86263 = 86390
- 151 + 86239 = 86390
Showing the first eight; more decompositions exist.
