Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51426, here are decompositions:
- 5 + 51421 = 51426
- 7 + 51419 = 51426
- 13 + 51413 = 51426
- 19 + 51407 = 51426
- 43 + 51383 = 51426
- 79 + 51347 = 51426
- 83 + 51343 = 51426
- 97 + 51329 = 51426
Showing the first eight; more decompositions exist.
