Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537922, here are decompositions:

19 + 31537903 = 31537922
61 + 31537861 = 31537922
79 + 31537843 = 31537922
181 + 31537741 = 31537922
313 + 31537609 = 31537922
331 + 31537591 = 31537922
349 + 31537573 = 31537922
379 + 31537543 = 31537922

Showing the first eight; more decompositions exist.
