Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015180, here are decompositions:
- 17 + 1015163 = 1015180
- 41 + 1015139 = 1015180
- 53 + 1015127 = 1015180
- 83 + 1015097 = 1015180
- 107 + 1015073 = 1015180
- 113 + 1015067 = 1015180
- 137 + 1015043 = 1015180
- 191 + 1014989 = 1015180
Showing the first eight; more decompositions exist.
