Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55538, here are decompositions:
- 37 + 55501 = 55538
- 97 + 55441 = 55538
- 127 + 55411 = 55538
- 139 + 55399 = 55538
- 157 + 55381 = 55538
- 199 + 55339 = 55538
- 331 + 55207 = 55538
- 337 + 55201 = 55538
Showing the first eight; more decompositions exist.
