Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504398, here are decompositions:

11 + 31504387 = 31504398
31 + 31504367 = 31504398
41 + 31504357 = 31504398
47 + 31504351 = 31504398
71 + 31504327 = 31504398
179 + 31504219 = 31504398
197 + 31504201 = 31504398
269 + 31504129 = 31504398

Showing the first eight; more decompositions exist.
