Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538026, here are decompositions:

29 + 31537997 = 31538026
137 + 31537889 = 31538026
167 + 31537859 = 31538026
467 + 31537559 = 31538026
479 + 31537547 = 31538026
557 + 31537469 = 31538026
593 + 31537433 = 31538026
617 + 31537409 = 31538026

Showing the first eight; more decompositions exist.
