Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020042, here are decompositions:
- 5 + 1020037 = 1020042
- 19 + 1020023 = 1020042
- 29 + 1020013 = 1020042
- 31 + 1020011 = 1020042
- 41 + 1020001 = 1020042
- 71 + 1019971 = 1020042
- 139 + 1019903 = 1020042
- 181 + 1019861 = 1020042
Showing the first eight; more decompositions exist.
