Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187970, here are decompositions:

7 + 187963 = 187970
19 + 187951 = 187970
43 + 187927 = 187970
61 + 187909 = 187970
73 + 187897 = 187970
109 + 187861 = 187970
127 + 187843 = 187970
271 + 187699 = 187970

Showing the first eight; more decompositions exist.
