Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042100, here are decompositions:
- 13 + 1042087 = 1042100
- 19 + 1042081 = 1042100
- 61 + 1042039 = 1042100
- 79 + 1042021 = 1042100
- 109 + 1041991 = 1042100
- 139 + 1041961 = 1042100
- 151 + 1041949 = 1042100
- 181 + 1041919 = 1042100
Showing the first eight; more decompositions exist.
