Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576946, here are decompositions:

103 + 31576843 = 31576946
307 + 31576639 = 31576946
367 + 31576579 = 31576946
397 + 31576549 = 31576946
463 + 31576483 = 31576946
487 + 31576459 = 31576946
727 + 31576219 = 31576946
829 + 31576117 = 31576946

Showing the first eight; more decompositions exist.
