Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506070, here are decompositions:
- 41 + 31506029 = 31506070
- 131 + 31505939 = 31506070
- 149 + 31505921 = 31506070
- 227 + 31505843 = 31506070
- 257 + 31505813 = 31506070
- 263 + 31505807 = 31506070
- 269 + 31505801 = 31506070
- 347 + 31505723 = 31506070
Showing the first eight; more decompositions exist.
