Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576698, here are decompositions:

17 + 31576681 = 31576698
59 + 31576639 = 31576698
79 + 31576619 = 31576698
149 + 31576549 = 31576698
157 + 31576541 = 31576698
239 + 31576459 = 31576698
271 + 31576427 = 31576698
281 + 31576417 = 31576698

Showing the first eight; more decompositions exist.
