Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523522, here are decompositions:

61 + 31523461 = 31523522
103 + 31523419 = 31523522
193 + 31523329 = 31523522
229 + 31523293 = 31523522
271 + 31523251 = 31523522
313 + 31523209 = 31523522
379 + 31523143 = 31523522
409 + 31523113 = 31523522

Showing the first eight; more decompositions exist.
