Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42524, here are decompositions:
- 37 + 42487 = 42524
- 61 + 42463 = 42524
- 67 + 42457 = 42524
- 73 + 42451 = 42524
- 127 + 42397 = 42524
- 151 + 42373 = 42524
- 193 + 42331 = 42524
- 241 + 42283 = 42524
Showing the first eight; more decompositions exist.
