Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538626, here are decompositions:

3 + 31538623 = 31538626
47 + 31538579 = 31538626
137 + 31538489 = 31538626
149 + 31538477 = 31538626
293 + 31538333 = 31538626
419 + 31538207 = 31538626
563 + 31538063 = 31538626
593 + 31538033 = 31538626

Showing the first eight; more decompositions exist.
