Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730148, here are decompositions:

71 + 8730077 = 8730148
149 + 8729999 = 8730148
281 + 8729867 = 8730148
311 + 8729837 = 8730148
347 + 8729801 = 8730148
419 + 8729729 = 8730148
431 + 8729717 = 8730148
467 + 8729681 = 8730148

Showing the first eight; more decompositions exist.
