Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523602, here are decompositions:

3 + 31523599 = 31523602
23 + 31523579 = 31523602
191 + 31523411 = 31523602
293 + 31523309 = 31523602
359 + 31523243 = 31523602
401 + 31523201 = 31523602
491 + 31523111 = 31523602
503 + 31523099 = 31523602

Showing the first eight; more decompositions exist.
