Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544802, here are decompositions:

19 + 31544783 = 31544802
31 + 31544771 = 31544802
43 + 31544759 = 31544802
53 + 31544749 = 31544802
83 + 31544719 = 31544802
89 + 31544713 = 31544802
229 + 31544573 = 31544802
241 + 31544561 = 31544802

Showing the first eight; more decompositions exist.
