Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17618, here are decompositions:
- 19 + 17599 = 17618
- 37 + 17581 = 17618
- 67 + 17551 = 17618
- 79 + 17539 = 17618
- 109 + 17509 = 17618
- 127 + 17491 = 17618
- 151 + 17467 = 17618
- 199 + 17419 = 17618
Showing the first eight; more decompositions exist.
