Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187072, here are decompositions:

3 + 187069 = 187072
5 + 187067 = 187072
23 + 187049 = 187072
29 + 187043 = 187072
113 + 186959 = 187072
311 + 186761 = 187072
383 + 186689 = 187072
401 + 186671 = 187072

Showing the first eight; more decompositions exist.
