Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83156, here are decompositions:
- 19 + 83137 = 83156
- 67 + 83089 = 83156
- 79 + 83077 = 83156
- 97 + 83059 = 83156
- 109 + 83047 = 83156
- 193 + 82963 = 83156
- 397 + 82759 = 83156
- 433 + 82723 = 83156
Showing the first eight; more decompositions exist.
