Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87924, here are decompositions:
- 7 + 87917 = 87924
- 13 + 87911 = 87924
- 37 + 87887 = 87924
- 43 + 87881 = 87924
- 47 + 87877 = 87924
- 71 + 87853 = 87924
- 113 + 87811 = 87924
- 127 + 87797 = 87924
Showing the first eight; more decompositions exist.
