Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42476, here are decompositions:
- 3 + 42473 = 42476
- 13 + 42463 = 42476
- 19 + 42457 = 42476
- 43 + 42433 = 42476
- 67 + 42409 = 42476
- 73 + 42403 = 42476
- 79 + 42397 = 42476
- 97 + 42379 = 42476
Showing the first eight; more decompositions exist.
