Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75990, here are decompositions:
- 7 + 75983 = 75990
- 11 + 75979 = 75990
- 23 + 75967 = 75990
- 53 + 75937 = 75990
- 59 + 75931 = 75990
- 107 + 75883 = 75990
- 137 + 75853 = 75990
- 157 + 75833 = 75990
Showing the first eight; more decompositions exist.
