Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542360, here are decompositions:
- 19 + 31542341 = 31542360
- 37 + 31542323 = 31542360
- 79 + 31542281 = 31542360
- 127 + 31542233 = 31542360
- 131 + 31542229 = 31542360
- 163 + 31542197 = 31542360
- 197 + 31542163 = 31542360
- 211 + 31542149 = 31542360
Showing the first eight; more decompositions exist.
