Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489484, here are decompositions:

67 + 31489417 = 31489484
73 + 31489411 = 31489484
241 + 31489243 = 31489484
307 + 31489177 = 31489484
337 + 31489147 = 31489484
421 + 31489063 = 31489484
457 + 31489027 = 31489484
577 + 31488907 = 31489484

Showing the first eight; more decompositions exist.
