Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51504, here are decompositions:
- 17 + 51487 = 51504
- 23 + 51481 = 51504
- 31 + 51473 = 51504
- 43 + 51461 = 51504
- 67 + 51437 = 51504
- 73 + 51431 = 51504
- 83 + 51421 = 51504
- 97 + 51407 = 51504
Showing the first eight; more decompositions exist.
