Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90040, here are decompositions:
- 17 + 90023 = 90040
- 23 + 90017 = 90040
- 29 + 90011 = 90040
- 101 + 89939 = 90040
- 131 + 89909 = 90040
- 149 + 89891 = 90040
- 173 + 89867 = 90040
- 191 + 89849 = 90040
Showing the first eight; more decompositions exist.
