Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543586, here are decompositions:

7 + 31543579 = 31543586
43 + 31543543 = 31543586
97 + 31543489 = 31543586
157 + 31543429 = 31543586
313 + 31543273 = 31543586
367 + 31543219 = 31543586
379 + 31543207 = 31543586
577 + 31543009 = 31543586

Showing the first eight; more decompositions exist.
