Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606652, here are decompositions:

73 + 31606579 = 31606652
109 + 31606543 = 31606652
223 + 31606429 = 31606652
229 + 31606423 = 31606652
241 + 31606411 = 31606652
271 + 31606381 = 31606652
283 + 31606369 = 31606652
313 + 31606339 = 31606652

Showing the first eight; more decompositions exist.
