Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489544, here are decompositions:

3 + 31489541 = 31489544
127 + 31489417 = 31489544
181 + 31489363 = 31489544
367 + 31489177 = 31489544
397 + 31489147 = 31489544
613 + 31488931 = 31489544
811 + 31488733 = 31489544
997 + 31488547 = 31489544

Showing the first eight; more decompositions exist.
