Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42554, here are decompositions:
- 67 + 42487 = 42554
- 97 + 42457 = 42554
- 103 + 42451 = 42554
- 151 + 42403 = 42554
- 157 + 42397 = 42554
- 163 + 42391 = 42554
- 181 + 42373 = 42554
- 223 + 42331 = 42554
Showing the first eight; more decompositions exist.
