Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564274, here are decompositions:
- 3 + 31564271 = 31564274
- 13 + 31564261 = 31564274
- 31 + 31564243 = 31564274
- 37 + 31564237 = 31564274
- 67 + 31564207 = 31564274
- 103 + 31564171 = 31564274
- 127 + 31564147 = 31564274
- 223 + 31564051 = 31564274
Showing the first eight; more decompositions exist.
