Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88780, here are decompositions:
- 59 + 88721 = 88780
- 113 + 88667 = 88780
- 137 + 88643 = 88780
- 173 + 88607 = 88780
- 191 + 88589 = 88780
- 233 + 88547 = 88780
- 257 + 88523 = 88780
- 281 + 88499 = 88780
Showing the first eight; more decompositions exist.
