Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42494, here are decompositions:
- 3 + 42491 = 42494
- 7 + 42487 = 42494
- 31 + 42463 = 42494
- 37 + 42457 = 42494
- 43 + 42451 = 42494
- 61 + 42433 = 42494
- 97 + 42397 = 42494
- 103 + 42391 = 42494
Showing the first eight; more decompositions exist.
