Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45542, here are decompositions:
- 19 + 45523 = 45542
- 61 + 45481 = 45542
- 103 + 45439 = 45542
- 109 + 45433 = 45542
- 139 + 45403 = 45542
- 181 + 45361 = 45542
- 199 + 45343 = 45542
- 223 + 45319 = 45542
Showing the first eight; more decompositions exist.
