Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99438, here are decompositions:
- 7 + 99431 = 99438
- 29 + 99409 = 99438
- 37 + 99401 = 99438
- 41 + 99397 = 99438
- 47 + 99391 = 99438
- 61 + 99377 = 99438
- 67 + 99371 = 99438
- 71 + 99367 = 99438
Showing the first eight; more decompositions exist.
