Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45500, here are decompositions:
- 3 + 45497 = 45500
- 19 + 45481 = 45500
- 61 + 45439 = 45500
- 67 + 45433 = 45500
- 73 + 45427 = 45500
- 97 + 45403 = 45500
- 139 + 45361 = 45500
- 157 + 45343 = 45500
Showing the first eight; more decompositions exist.
