Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84438, here are decompositions:
- 7 + 84431 = 84438
- 17 + 84421 = 84438
- 31 + 84407 = 84438
- 37 + 84401 = 84438
- 47 + 84391 = 84438
- 61 + 84377 = 84438
- 89 + 84349 = 84438
- 131 + 84307 = 84438
Showing the first eight; more decompositions exist.
