Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98784, here are decompositions:
- 5 + 98779 = 98784
- 11 + 98773 = 98784
- 47 + 98737 = 98784
- 53 + 98731 = 98784
- 67 + 98717 = 98784
- 71 + 98713 = 98784
- 73 + 98711 = 98784
- 157 + 98627 = 98784
Showing the first eight; more decompositions exist.
