Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5388, here are decompositions:
- 7 + 5381 = 5388
- 37 + 5351 = 5388
- 41 + 5347 = 5388
- 79 + 5309 = 5388
- 107 + 5281 = 5388
- 109 + 5279 = 5388
- 127 + 5261 = 5388
- 151 + 5237 = 5388
Showing the first eight; more decompositions exist.
