Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489448, here are decompositions:

31 + 31489417 = 31489448
37 + 31489411 = 31489448
271 + 31489177 = 31489448
379 + 31489069 = 31489448
421 + 31489027 = 31489448
439 + 31489009 = 31489448
457 + 31488991 = 31489448
541 + 31488907 = 31489448

Showing the first eight; more decompositions exist.
