Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015688, here are decompositions:
- 61 + 1015627 = 1015688
- 127 + 1015561 = 1015688
- 139 + 1015549 = 1015688
- 181 + 1015507 = 1015688
- 229 + 1015459 = 1015688
- 379 + 1015309 = 1015688
- 607 + 1015081 = 1015688
- 631 + 1015057 = 1015688
Showing the first eight; more decompositions exist.
