Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55982, here are decompositions:
- 61 + 55921 = 55982
- 79 + 55903 = 55982
- 139 + 55843 = 55982
- 163 + 55819 = 55982
- 271 + 55711 = 55982
- 349 + 55633 = 55982
- 373 + 55609 = 55982
- 379 + 55603 = 55982
Showing the first eight; more decompositions exist.
