Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51424, here are decompositions:
- 3 + 51421 = 51424
- 5 + 51419 = 51424
- 11 + 51413 = 51424
- 17 + 51407 = 51424
- 41 + 51383 = 51424
- 83 + 51341 = 51424
- 137 + 51287 = 51424
- 167 + 51257 = 51424
Showing the first eight; more decompositions exist.
