Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75438, here are decompositions:
- 7 + 75431 = 75438
- 31 + 75407 = 75438
- 37 + 75401 = 75438
- 47 + 75391 = 75438
- 61 + 75377 = 75438
- 71 + 75367 = 75438
- 101 + 75337 = 75438
- 109 + 75329 = 75438
Showing the first eight; more decompositions exist.
