Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538498, here are decompositions:

7 + 31538491 = 31538498
127 + 31538371 = 31538498
337 + 31538161 = 31538498
367 + 31538131 = 31538498
499 + 31537999 = 31538498
577 + 31537921 = 31538498
661 + 31537837 = 31538498
751 + 31537747 = 31538498

Showing the first eight; more decompositions exist.
