Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461750, here are decompositions:
- 7 + 31461743 = 31461750
- 13 + 31461737 = 31461750
- 53 + 31461697 = 31461750
- 97 + 31461653 = 31461750
- 109 + 31461641 = 31461750
- 179 + 31461571 = 31461750
- 181 + 31461569 = 31461750
- 193 + 31461557 = 31461750
Showing the first eight; more decompositions exist.
