Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502448, here are decompositions:

7 + 31502441 = 31502448
17 + 31502431 = 31502448
137 + 31502311 = 31502448
179 + 31502269 = 31502448
317 + 31502131 = 31502448
349 + 31502099 = 31502448
491 + 31501957 = 31502448
541 + 31501907 = 31502448

Showing the first eight; more decompositions exist.
