Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547750, here are decompositions:
- 19 + 31547731 = 31547750
- 43 + 31547707 = 31547750
- 67 + 31547683 = 31547750
- 79 + 31547671 = 31547750
- 109 + 31547641 = 31547750
- 193 + 31547557 = 31547750
- 211 + 31547539 = 31547750
- 271 + 31547479 = 31547750
Showing the first eight; more decompositions exist.
