Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484930, here are decompositions:

19 + 31484911 = 31484930
67 + 31484863 = 31484930
109 + 31484821 = 31484930
283 + 31484647 = 31484930
313 + 31484617 = 31484930
397 + 31484533 = 31484930
571 + 31484359 = 31484930
577 + 31484353 = 31484930

Showing the first eight; more decompositions exist.
