Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446848, here are decompositions:

79 + 31446769 = 31446848
109 + 31446739 = 31446848
241 + 31446607 = 31446848
409 + 31446439 = 31446848
421 + 31446427 = 31446848
487 + 31446361 = 31446848
607 + 31446241 = 31446848
619 + 31446229 = 31446848

Showing the first eight; more decompositions exist.
