Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53218, here are decompositions:
- 17 + 53201 = 53218
- 29 + 53189 = 53218
- 47 + 53171 = 53218
- 71 + 53147 = 53218
- 89 + 53129 = 53218
- 101 + 53117 = 53218
- 131 + 53087 = 53218
- 149 + 53069 = 53218
Showing the first eight; more decompositions exist.
