Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4520, here are decompositions:
- 3 + 4517 = 4520
- 7 + 4513 = 4520
- 13 + 4507 = 4520
- 37 + 4483 = 4520
- 73 + 4447 = 4520
- 79 + 4441 = 4520
- 97 + 4423 = 4520
- 157 + 4363 = 4520
Showing the first eight; more decompositions exist.
