Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577048, here are decompositions:

31 + 31577017 = 31577048
157 + 31576891 = 31577048
271 + 31576777 = 31577048
367 + 31576681 = 31577048
409 + 31576639 = 31577048
499 + 31576549 = 31577048
571 + 31576477 = 31577048
631 + 31576417 = 31577048

Showing the first eight; more decompositions exist.
