Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187030, here are decompositions:

3 + 187027 = 187030
71 + 186959 = 187030
83 + 186947 = 187030
113 + 186917 = 187030
257 + 186773 = 187030
269 + 186761 = 187030
359 + 186671 = 187030
383 + 186647 = 187030

Showing the first eight; more decompositions exist.
