Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501602, here are decompositions:

19 + 31501583 = 31501602
71 + 31501531 = 31501602
79 + 31501523 = 31501602
193 + 31501409 = 31501602
199 + 31501403 = 31501602
241 + 31501361 = 31501602
269 + 31501333 = 31501602
271 + 31501331 = 31501602

Showing the first eight; more decompositions exist.
