Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520160, here are decompositions:
- 19 + 31520141 = 31520160
- 41 + 31520119 = 31520160
- 43 + 31520117 = 31520160
- 71 + 31520089 = 31520160
- 101 + 31520059 = 31520160
- 131 + 31520029 = 31520160
- 149 + 31520011 = 31520160
- 151 + 31520009 = 31520160
Showing the first eight; more decompositions exist.
