Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537152, here are decompositions:
- 5 + 31537147 = 31537152
- 19 + 31537133 = 31537152
- 103 + 31537049 = 31537152
- 109 + 31537043 = 31537152
- 113 + 31537039 = 31537152
- 149 + 31537003 = 31537152
- 151 + 31537001 = 31537152
- 193 + 31536959 = 31537152
Showing the first eight; more decompositions exist.
