Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77472, here are decompositions:
- 41 + 77431 = 77472
- 53 + 77419 = 77472
- 89 + 77383 = 77472
- 103 + 77369 = 77472
- 113 + 77359 = 77472
- 149 + 77323 = 77472
- 181 + 77291 = 77472
- 193 + 77279 = 77472
Showing the first eight; more decompositions exist.
