Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57438, here are decompositions:
- 11 + 57427 = 57438
- 41 + 57397 = 57438
- 71 + 57367 = 57438
- 89 + 57349 = 57438
- 107 + 57331 = 57438
- 109 + 57329 = 57438
- 137 + 57301 = 57438
- 151 + 57287 = 57438
Showing the first eight; more decompositions exist.
