Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553248, here are decompositions:
- 29 + 31553219 = 31553248
- 47 + 31553201 = 31553248
- 71 + 31553177 = 31553248
- 179 + 31553069 = 31553248
- 227 + 31553021 = 31553248
- 401 + 31552847 = 31553248
- 431 + 31552817 = 31553248
- 521 + 31552727 = 31553248
Showing the first eight; more decompositions exist.
