Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45770, here are decompositions:
- 3 + 45767 = 45770
- 7 + 45763 = 45770
- 13 + 45757 = 45770
- 19 + 45751 = 45770
- 73 + 45697 = 45770
- 79 + 45691 = 45770
- 97 + 45673 = 45770
- 103 + 45667 = 45770
Showing the first eight; more decompositions exist.
