Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51508, here are decompositions:
- 5 + 51503 = 51508
- 29 + 51479 = 51508
- 47 + 51461 = 51508
- 59 + 51449 = 51508
- 71 + 51437 = 51508
- 89 + 51419 = 51508
- 101 + 51407 = 51508
- 167 + 51341 = 51508
Showing the first eight; more decompositions exist.
