Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536424, here are decompositions:

41 + 31536383 = 31536424
71 + 31536353 = 31536424
131 + 31536293 = 31536424
137 + 31536287 = 31536424
197 + 31536227 = 31536424
263 + 31536161 = 31536424
443 + 31535981 = 31536424
593 + 31535831 = 31536424

Showing the first eight; more decompositions exist.
