Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504750, here are decompositions:
- 3 + 31504747 = 31504750
- 47 + 31504703 = 31504750
- 59 + 31504691 = 31504750
- 83 + 31504667 = 31504750
- 89 + 31504661 = 31504750
- 131 + 31504619 = 31504750
- 257 + 31504493 = 31504750
- 269 + 31504481 = 31504750
Showing the first eight; more decompositions exist.
