Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5618, here are decompositions:
- 37 + 5581 = 5618
- 61 + 5557 = 5618
- 97 + 5521 = 5618
- 139 + 5479 = 5618
- 181 + 5437 = 5618
- 199 + 5419 = 5618
- 211 + 5407 = 5618
- 271 + 5347 = 5618
Showing the first eight; more decompositions exist.
