Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987696, here are decompositions:
- 37 + 987659 = 987696
- 89 + 987607 = 987696
- 97 + 987599 = 987696
- 103 + 987593 = 987696
- 109 + 987587 = 987696
- 137 + 987559 = 987696
- 163 + 987533 = 987696
- 173 + 987523 = 987696
Showing the first eight; more decompositions exist.
