Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39490, here are decompositions:
- 29 + 39461 = 39490
- 47 + 39443 = 39490
- 71 + 39419 = 39490
- 107 + 39383 = 39490
- 131 + 39359 = 39490
- 149 + 39341 = 39490
- 167 + 39323 = 39490
- 173 + 39317 = 39490
Showing the first eight; more decompositions exist.
