Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540534, here are decompositions:

5 + 31540529 = 31540534
41 + 31540493 = 31540534
191 + 31540343 = 31540534
293 + 31540241 = 31540534
317 + 31540217 = 31540534
353 + 31540181 = 31540534
503 + 31540031 = 31540534
521 + 31540013 = 31540534

Showing the first eight; more decompositions exist.
