Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42500, here are decompositions:
- 13 + 42487 = 42500
- 37 + 42463 = 42500
- 43 + 42457 = 42500
- 67 + 42433 = 42500
- 97 + 42403 = 42500
- 103 + 42397 = 42500
- 109 + 42391 = 42500
- 127 + 42373 = 42500
Showing the first eight; more decompositions exist.
