Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987792, here are decompositions:
- 53 + 987739 = 987792
- 79 + 987713 = 987792
- 193 + 987599 = 987792
- 199 + 987593 = 987792
- 233 + 987559 = 987792
- 251 + 987541 = 987792
- 269 + 987523 = 987792
- 283 + 987509 = 987792
Showing the first eight; more decompositions exist.
