Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577006, here are decompositions:

163 + 31576843 = 31577006
229 + 31576777 = 31577006
367 + 31576639 = 31577006
457 + 31576549 = 31577006
523 + 31576483 = 31577006
547 + 31576459 = 31577006
739 + 31576267 = 31577006
787 + 31576219 = 31577006

Showing the first eight; more decompositions exist.
