Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020072, here are decompositions:
- 13 + 1020059 = 1020072
- 23 + 1020049 = 1020072
- 29 + 1020043 = 1020072
- 59 + 1020013 = 1020072
- 61 + 1020011 = 1020072
- 71 + 1020001 = 1020072
- 101 + 1019971 = 1020072
- 173 + 1019899 = 1020072
Showing the first eight; more decompositions exist.
