Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120904, here are decompositions:
- 5 + 120899 = 120904
- 41 + 120863 = 120904
- 53 + 120851 = 120904
- 71 + 120833 = 120904
- 137 + 120767 = 120904
- 167 + 120737 = 120904
- 191 + 120713 = 120904
- 227 + 120677 = 120904
Showing the first eight; more decompositions exist.
