Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78550, here are decompositions:
- 11 + 78539 = 78550
- 41 + 78509 = 78550
- 53 + 78497 = 78550
- 71 + 78479 = 78550
- 83 + 78467 = 78550
- 113 + 78437 = 78550
- 149 + 78401 = 78550
- 233 + 78317 = 78550
Showing the first eight; more decompositions exist.
