Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576622, here are decompositions:

3 + 31576619 = 31576622
43 + 31576579 = 31576622
73 + 31576549 = 31576622
139 + 31576483 = 31576622
163 + 31576459 = 31576622
211 + 31576411 = 31576622
271 + 31576351 = 31576622
421 + 31576201 = 31576622

Showing the first eight; more decompositions exist.
