Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531138, here are decompositions:
- 41 + 33531097 = 33531138
- 61 + 33531077 = 33531138
- 79 + 33531059 = 33531138
- 89 + 33531049 = 33531138
- 107 + 33531031 = 33531138
- 127 + 33531011 = 33531138
- 139 + 33530999 = 33531138
- 167 + 33530971 = 33531138
Showing the first eight; more decompositions exist.
