Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548740, here are decompositions:

7 + 31548733 = 31548740
43 + 31548697 = 31548740
127 + 31548613 = 31548740
163 + 31548577 = 31548740
193 + 31548547 = 31548740
241 + 31548499 = 31548740
313 + 31548427 = 31548740
397 + 31548343 = 31548740

Showing the first eight; more decompositions exist.
