Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76438, here are decompositions:
- 17 + 76421 = 76438
- 59 + 76379 = 76438
- 71 + 76367 = 76438
- 149 + 76289 = 76438
- 179 + 76259 = 76438
- 281 + 76157 = 76438
- 347 + 76091 = 76438
- 359 + 76079 = 76438
Showing the first eight; more decompositions exist.
