Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015308, here are decompositions:
- 31 + 1015277 = 1015308
- 101 + 1015207 = 1015308
- 109 + 1015199 = 1015308
- 137 + 1015171 = 1015308
- 149 + 1015159 = 1015308
- 181 + 1015127 = 1015308
- 211 + 1015097 = 1015308
- 227 + 1015081 = 1015308
Showing the first eight; more decompositions exist.
