Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25040, here are decompositions:
- 3 + 25037 = 25040
- 7 + 25033 = 25040
- 61 + 24979 = 25040
- 73 + 24967 = 25040
- 97 + 24943 = 25040
- 151 + 24889 = 25040
- 163 + 24877 = 25040
- 181 + 24859 = 25040
Showing the first eight; more decompositions exist.
