Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80578, here are decompositions:
- 11 + 80567 = 80578
- 41 + 80537 = 80578
- 89 + 80489 = 80578
- 107 + 80471 = 80578
- 131 + 80447 = 80578
- 149 + 80429 = 80578
- 191 + 80387 = 80578
- 269 + 80309 = 80578
Showing the first eight; more decompositions exist.
