Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51478, here are decompositions:
- 5 + 51473 = 51478
- 17 + 51461 = 51478
- 29 + 51449 = 51478
- 41 + 51437 = 51478
- 47 + 51431 = 51478
- 59 + 51419 = 51478
- 71 + 51407 = 51478
- 131 + 51347 = 51478
Showing the first eight; more decompositions exist.
