Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133542, here are decompositions:
- 23 + 133519 = 133542
- 43 + 133499 = 133542
- 61 + 133481 = 133542
- 103 + 133439 = 133542
- 139 + 133403 = 133542
- 151 + 133391 = 133542
- 163 + 133379 = 133542
- 191 + 133351 = 133542
Showing the first eight; more decompositions exist.
