Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015122, here are decompositions:
- 29 + 1015093 = 1015122
- 41 + 1015081 = 1015122
- 61 + 1015061 = 1015122
- 71 + 1015051 = 1015122
- 79 + 1015043 = 1015122
- 83 + 1015039 = 1015122
- 113 + 1015009 = 1015122
- 149 + 1014973 = 1015122
Showing the first eight; more decompositions exist.
