Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502424, here are decompositions:

53 + 31502371 = 31502424
61 + 31502363 = 31502424
71 + 31502353 = 31502424
113 + 31502311 = 31502424
137 + 31502287 = 31502424
181 + 31502243 = 31502424
211 + 31502213 = 31502424
241 + 31502183 = 31502424

Showing the first eight; more decompositions exist.
