Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494624, here are decompositions:

13 + 31494611 = 31494624
41 + 31494583 = 31494624
43 + 31494581 = 31494624
71 + 31494553 = 31494624
127 + 31494497 = 31494624
157 + 31494467 = 31494624
181 + 31494443 = 31494624
193 + 31494431 = 31494624

Showing the first eight; more decompositions exist.
