Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527952, here are decompositions:

11 + 31527941 = 31527952
251 + 31527701 = 31527952
263 + 31527689 = 31527952
293 + 31527659 = 31527952
383 + 31527569 = 31527952
419 + 31527533 = 31527952
431 + 31527521 = 31527952
461 + 31527491 = 31527952

Showing the first eight; more decompositions exist.
