Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52542, here are decompositions:
- 13 + 52529 = 52542
- 31 + 52511 = 52542
- 41 + 52501 = 52542
- 53 + 52489 = 52542
- 89 + 52453 = 52542
- 109 + 52433 = 52542
- 151 + 52391 = 52542
- 163 + 52379 = 52542
Showing the first eight; more decompositions exist.
