Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148272, here are decompositions:
- 23 + 148249 = 148272
- 29 + 148243 = 148272
- 43 + 148229 = 148272
- 71 + 148201 = 148272
- 73 + 148199 = 148272
- 79 + 148193 = 148272
- 101 + 148171 = 148272
- 149 + 148123 = 148272
Showing the first eight; more decompositions exist.
