Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576598, here are decompositions:

19 + 31576579 = 31576598
139 + 31576459 = 31576598
181 + 31576417 = 31576598
331 + 31576267 = 31576598
337 + 31576261 = 31576598
367 + 31576231 = 31576598
379 + 31576219 = 31576598
397 + 31576201 = 31576598

Showing the first eight; more decompositions exist.
