Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502372, here are decompositions:

19 + 31502353 = 31502372
43 + 31502329 = 31502372
61 + 31502311 = 31502372
103 + 31502269 = 31502372
211 + 31502161 = 31502372
241 + 31502131 = 31502372
523 + 31501849 = 31502372
541 + 31501831 = 31502372

Showing the first eight; more decompositions exist.
