Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487324, here are decompositions:

7 + 31487317 = 31487324
13 + 31487311 = 31487324
61 + 31487263 = 31487324
73 + 31487251 = 31487324
181 + 31487143 = 31487324
397 + 31486927 = 31487324
601 + 31486723 = 31487324
613 + 31486711 = 31487324

Showing the first eight; more decompositions exist.
