Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613532, here are decompositions:

19 + 31613513 = 31613532
131 + 31613401 = 31613532
149 + 31613383 = 31613532
191 + 31613341 = 31613532
199 + 31613333 = 31613532
241 + 31613291 = 31613532
283 + 31613249 = 31613532
389 + 31613143 = 31613532

Showing the first eight; more decompositions exist.
