Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749272, here are decompositions:
- 29 + 8749243 = 8749272
- 43 + 8749229 = 8749272
- 53 + 8749219 = 8749272
- 73 + 8749199 = 8749272
- 109 + 8749163 = 8749272
- 131 + 8749141 = 8749272
- 139 + 8749133 = 8749272
- 151 + 8749121 = 8749272
Showing the first eight; more decompositions exist.
