Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546250, here are decompositions:

19 + 31546231 = 31546250
97 + 31546153 = 31546250
139 + 31546111 = 31546250
181 + 31546069 = 31546250
331 + 31545919 = 31546250
349 + 31545901 = 31546250
409 + 31545841 = 31546250
487 + 31545763 = 31546250

Showing the first eight; more decompositions exist.
