Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544980, here are decompositions:

11 + 31544969 = 31544980
17 + 31544963 = 31544980
101 + 31544879 = 31544980
197 + 31544783 = 31544980
263 + 31544717 = 31544980
419 + 31544561 = 31544980
449 + 31544531 = 31544980
563 + 31544417 = 31544980

Showing the first eight; more decompositions exist.
