Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40578, here are decompositions:
- 19 + 40559 = 40578
- 47 + 40531 = 40578
- 59 + 40519 = 40578
- 71 + 40507 = 40578
- 79 + 40499 = 40578
- 107 + 40471 = 40578
- 149 + 40429 = 40578
- 151 + 40427 = 40578
Showing the first eight; more decompositions exist.
