Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502436, here are decompositions:
- 5 + 31502431 = 31502436
- 73 + 31502363 = 31502436
- 83 + 31502353 = 31502436
- 103 + 31502333 = 31502436
- 107 + 31502329 = 31502436
- 149 + 31502287 = 31502436
- 157 + 31502279 = 31502436
- 167 + 31502269 = 31502436
Showing the first eight; more decompositions exist.
