Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127380, here are decompositions:
- 7 + 127373 = 127380
- 17 + 127363 = 127380
- 37 + 127343 = 127380
- 59 + 127321 = 127380
- 79 + 127301 = 127380
- 83 + 127297 = 127380
- 89 + 127291 = 127380
- 103 + 127277 = 127380
Showing the first eight; more decompositions exist.
