Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504200, here are decompositions:
- 11 + 31504189 = 31504200
- 17 + 31504183 = 31504200
- 67 + 31504133 = 31504200
- 71 + 31504129 = 31504200
- 73 + 31504127 = 31504200
- 97 + 31504103 = 31504200
- 103 + 31504097 = 31504200
- 113 + 31504087 = 31504200
Showing the first eight; more decompositions exist.
