Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015868, here are decompositions:
- 241 + 1015627 = 1015868
- 307 + 1015561 = 1015868
- 367 + 1015501 = 1015868
- 397 + 1015471 = 1015868
- 409 + 1015459 = 1015868
- 499 + 1015369 = 1015868
- 661 + 1015207 = 1015868
- 709 + 1015159 = 1015868
Showing the first eight; more decompositions exist.
