Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576322, here are decompositions:

61 + 31576261 = 31576322
103 + 31576219 = 31576322
313 + 31576009 = 31576322
331 + 31575991 = 31576322
499 + 31575823 = 31576322
523 + 31575799 = 31576322
751 + 31575571 = 31576322
769 + 31575553 = 31576322

Showing the first eight; more decompositions exist.
