Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90972, here are decompositions:
- 41 + 90931 = 90972
- 61 + 90911 = 90972
- 71 + 90901 = 90972
- 109 + 90863 = 90972
- 131 + 90841 = 90972
- 139 + 90833 = 90972
- 149 + 90823 = 90972
- 151 + 90821 = 90972
Showing the first eight; more decompositions exist.
