Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939880, here are decompositions:
- 41 + 939839 = 939880
- 89 + 939791 = 939880
- 107 + 939773 = 939880
- 113 + 939767 = 939880
- 131 + 939749 = 939880
- 167 + 939713 = 939880
- 173 + 939707 = 939880
- 257 + 939623 = 939880
Showing the first eight; more decompositions exist.
