Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521326, here are decompositions:

97 + 31521229 = 31521326
103 + 31521223 = 31521326
349 + 31520977 = 31521326
367 + 31520959 = 31521326
409 + 31520917 = 31521326
607 + 31520719 = 31521326
709 + 31520617 = 31521326
757 + 31520569 = 31521326

Showing the first eight; more decompositions exist.
