Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590444, here are decompositions:

23 + 31590421 = 31590444
31 + 31590413 = 31590444
43 + 31590401 = 31590444
47 + 31590397 = 31590444
73 + 31590371 = 31590444
101 + 31590343 = 31590444
131 + 31590313 = 31590444
167 + 31590277 = 31590444

Showing the first eight; more decompositions exist.
