Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576616, here are decompositions:

37 + 31576579 = 31576616
67 + 31576549 = 31576616
139 + 31576477 = 31576616
157 + 31576459 = 31576616
163 + 31576453 = 31576616
199 + 31576417 = 31576616
349 + 31576267 = 31576616
397 + 31576219 = 31576616

Showing the first eight; more decompositions exist.
