Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87798, here are decompositions:
- 5 + 87793 = 87798
- 31 + 87767 = 87798
- 47 + 87751 = 87798
- 59 + 87739 = 87798
- 79 + 87719 = 87798
- 97 + 87701 = 87798
- 101 + 87697 = 87798
- 107 + 87691 = 87798
Showing the first eight; more decompositions exist.
