Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22542, here are decompositions:
- 11 + 22531 = 22542
- 31 + 22511 = 22542
- 41 + 22501 = 22542
- 59 + 22483 = 22542
- 61 + 22481 = 22542
- 73 + 22469 = 22542
- 89 + 22453 = 22542
- 101 + 22441 = 22542
Showing the first eight; more decompositions exist.
