Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546028, here are decompositions:
- 37 + 31545991 = 31546028
- 109 + 31545919 = 31546028
- 127 + 31545901 = 31546028
- 421 + 31545607 = 31546028
- 541 + 31545487 = 31546028
- 937 + 31545091 = 31546028
- 967 + 31545061 = 31546028
- 1087 + 31544941 = 31546028
Showing the first eight; more decompositions exist.
