Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527526, here are decompositions:

3 + 31527523 = 31527526
5 + 31527521 = 31527526
29 + 31527497 = 31527526
113 + 31527413 = 31527526
137 + 31527389 = 31527526
293 + 31527233 = 31527526
353 + 31527173 = 31527526
383 + 31527143 = 31527526

Showing the first eight; more decompositions exist.
