Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4512, here are decompositions:
- 5 + 4507 = 4512
- 19 + 4493 = 4512
- 29 + 4483 = 4512
- 31 + 4481 = 4512
- 61 + 4451 = 4512
- 71 + 4441 = 4512
- 89 + 4423 = 4512
- 103 + 4409 = 4512
Showing the first eight; more decompositions exist.
