Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506694, here are decompositions:

5 + 31506689 = 31506694
17 + 31506677 = 31506694
53 + 31506641 = 31506694
173 + 31506521 = 31506694
251 + 31506443 = 31506694
257 + 31506437 = 31506694
383 + 31506311 = 31506694
431 + 31506263 = 31506694

Showing the first eight; more decompositions exist.
