Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541522, here are decompositions:

13 + 31541509 = 31541522
73 + 31541449 = 31541522
163 + 31541359 = 31541522
241 + 31541281 = 31541522
349 + 31541173 = 31541522
409 + 31541113 = 31541522
421 + 31541101 = 31541522
601 + 31540921 = 31541522

Showing the first eight; more decompositions exist.
