Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187946, here are decompositions:

19 + 187927 = 187946
37 + 187909 = 187946
103 + 187843 = 187946
277 + 187669 = 187946
307 + 187639 = 187946
313 + 187633 = 187946
349 + 187597 = 187946
373 + 187573 = 187946

Showing the first eight; more decompositions exist.
