Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3618, here are decompositions:
- 5 + 3613 = 3618
- 11 + 3607 = 3618
- 37 + 3581 = 3618
- 47 + 3571 = 3618
- 59 + 3559 = 3618
- 61 + 3557 = 3618
- 71 + 3547 = 3618
- 79 + 3539 = 3618
Showing the first eight; more decompositions exist.
