Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520492, here are decompositions:

13 + 31520479 = 31520492
103 + 31520389 = 31520492
139 + 31520353 = 31520492
193 + 31520299 = 31520492
313 + 31520179 = 31520492
373 + 31520119 = 31520492
433 + 31520059 = 31520492
463 + 31520029 = 31520492

Showing the first eight; more decompositions exist.
