Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118580, here are decompositions:
- 31 + 118549 = 118580
- 37 + 118543 = 118580
- 109 + 118471 = 118580
- 127 + 118453 = 118580
- 151 + 118429 = 118580
- 157 + 118423 = 118580
- 181 + 118399 = 118580
- 193 + 118387 = 118580
Showing the first eight; more decompositions exist.
