Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522934, here are decompositions:

61 + 31522873 = 31522934
241 + 31522693 = 31522934
271 + 31522663 = 31522934
277 + 31522657 = 31522934
337 + 31522597 = 31522934
523 + 31522411 = 31522934
571 + 31522363 = 31522934
577 + 31522357 = 31522934

Showing the first eight; more decompositions exist.
