Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75478, here are decompositions:
- 41 + 75437 = 75478
- 47 + 75431 = 75478
- 71 + 75407 = 75478
- 89 + 75389 = 75478
- 101 + 75377 = 75478
- 131 + 75347 = 75478
- 149 + 75329 = 75478
- 239 + 75239 = 75478
Showing the first eight; more decompositions exist.
