Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521334, here are decompositions:

23 + 31521311 = 31521334
107 + 31521227 = 31521334
191 + 31521143 = 31521334
281 + 31521053 = 31521334
587 + 31520747 = 31521334
797 + 31520537 = 31521334
881 + 31520453 = 31521334
941 + 31520393 = 31521334

Showing the first eight; more decompositions exist.
