Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75472, here are decompositions:
- 41 + 75431 = 75472
- 71 + 75401 = 75472
- 83 + 75389 = 75472
- 149 + 75323 = 75472
- 233 + 75239 = 75472
- 263 + 75209 = 75472
- 311 + 75161 = 75472
- 389 + 75083 = 75472
Showing the first eight; more decompositions exist.
