Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72290, here are decompositions:
- 3 + 72287 = 72290
- 13 + 72277 = 72290
- 19 + 72271 = 72290
- 37 + 72253 = 72290
- 61 + 72229 = 72290
- 67 + 72223 = 72290
- 79 + 72211 = 72290
- 151 + 72139 = 72290
Showing the first eight; more decompositions exist.
