Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55542, here are decompositions:
- 13 + 55529 = 55542
- 31 + 55511 = 55542
- 41 + 55501 = 55542
- 73 + 55469 = 55542
- 101 + 55441 = 55542
- 103 + 55439 = 55542
- 131 + 55411 = 55542
- 191 + 55351 = 55542
Showing the first eight; more decompositions exist.
