Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546448, here are decompositions:

61 + 31546387 = 31546448
79 + 31546369 = 31546448
97 + 31546351 = 31546448
181 + 31546267 = 31546448
337 + 31546111 = 31546448
379 + 31546069 = 31546448
457 + 31545991 = 31546448
547 + 31545901 = 31546448

Showing the first eight; more decompositions exist.
