Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523452, here are decompositions:

11 + 31523441 = 31523452
41 + 31523411 = 31523452
53 + 31523399 = 31523452
71 + 31523381 = 31523452
173 + 31523279 = 31523452
251 + 31523201 = 31523452
353 + 31523099 = 31523452
431 + 31523021 = 31523452

Showing the first eight; more decompositions exist.
