Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545444, here are decompositions:

5 + 31545439 = 31545444
37 + 31545407 = 31545444
43 + 31545401 = 31545444
53 + 31545391 = 31545444
71 + 31545373 = 31545444
101 + 31545343 = 31545444
113 + 31545331 = 31545444
127 + 31545317 = 31545444

Showing the first eight; more decompositions exist.
