Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546418, here are decompositions:

31 + 31546387 = 31546418
67 + 31546351 = 31546418
139 + 31546279 = 31546418
151 + 31546267 = 31546418
307 + 31546111 = 31546418
349 + 31546069 = 31546418
499 + 31545919 = 31546418
577 + 31545841 = 31546418

Showing the first eight; more decompositions exist.
