Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021992, here are decompositions:
- 19 + 1021973 = 1021992
- 29 + 1021963 = 1021992
- 31 + 1021961 = 1021992
- 73 + 1021919 = 1021992
- 113 + 1021879 = 1021992
- 131 + 1021861 = 1021992
- 193 + 1021799 = 1021992
- 199 + 1021793 = 1021992
Showing the first eight; more decompositions exist.
