Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576958, here are decompositions:

67 + 31576891 = 31576958
181 + 31576777 = 31576958
199 + 31576759 = 31576958
277 + 31576681 = 31576958
379 + 31576579 = 31576958
409 + 31576549 = 31576958
499 + 31576459 = 31576958
541 + 31576417 = 31576958

Showing the first eight; more decompositions exist.
