Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987764, here are decompositions:
- 67 + 987697 = 987764
- 157 + 987607 = 987764
- 223 + 987541 = 987764
- 241 + 987523 = 987764
- 307 + 987457 = 987764
- 331 + 987433 = 987764
- 373 + 987391 = 987764
- 571 + 987193 = 987764
Showing the first eight; more decompositions exist.
