Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548248, here are decompositions:

139 + 31548109 = 31548248
241 + 31548007 = 31548248
331 + 31547917 = 31548248
397 + 31547851 = 31548248
409 + 31547839 = 31548248
499 + 31547749 = 31548248
541 + 31547707 = 31548248
547 + 31547701 = 31548248

Showing the first eight; more decompositions exist.
