Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042020, here are decompositions:
- 19 + 1042001 = 1042020
- 29 + 1041991 = 1042020
- 37 + 1041983 = 1042020
- 59 + 1041961 = 1042020
- 71 + 1041949 = 1042020
- 101 + 1041919 = 1042020
- 113 + 1041907 = 1042020
- 127 + 1041893 = 1042020
Showing the first eight; more decompositions exist.
