Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576350, here are decompositions:
- 61 + 31576289 = 31576350
- 67 + 31576283 = 31576350
- 83 + 31576267 = 31576350
- 89 + 31576261 = 31576350
- 97 + 31576253 = 31576350
- 109 + 31576241 = 31576350
- 131 + 31576219 = 31576350
- 139 + 31576211 = 31576350
Showing the first eight; more decompositions exist.
