Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55778, here are decompositions:
- 61 + 55717 = 55778
- 67 + 55711 = 55778
- 97 + 55681 = 55778
- 139 + 55639 = 55778
- 157 + 55621 = 55778
- 199 + 55579 = 55778
- 277 + 55501 = 55778
- 337 + 55441 = 55778
Showing the first eight; more decompositions exist.
