Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538746, here are decompositions:

3 + 31538743 = 31538746
17 + 31538729 = 31538746
53 + 31538693 = 31538746
167 + 31538579 = 31538746
257 + 31538489 = 31538746
269 + 31538477 = 31538746
419 + 31538327 = 31538746
593 + 31538153 = 31538746

Showing the first eight; more decompositions exist.
