Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55772, here are decompositions:
- 61 + 55711 = 55772
- 109 + 55663 = 55772
- 139 + 55633 = 55772
- 151 + 55621 = 55772
- 163 + 55609 = 55772
- 193 + 55579 = 55772
- 271 + 55501 = 55772
- 331 + 55441 = 55772
Showing the first eight; more decompositions exist.
