Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535212, here are decompositions:
- 29 + 31535183 = 31535212
- 41 + 31535171 = 31535212
- 89 + 31535123 = 31535212
- 131 + 31535081 = 31535212
- 179 + 31535033 = 31535212
- 251 + 31534961 = 31535212
- 461 + 31534751 = 31535212
- 503 + 31534709 = 31535212
Showing the first eight; more decompositions exist.
