Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188812, here are decompositions:

11 + 188801 = 188812
59 + 188753 = 188812
83 + 188729 = 188812
101 + 188711 = 188812
131 + 188681 = 188812
179 + 188633 = 188812
191 + 188621 = 188812
233 + 188579 = 188812

Showing the first eight; more decompositions exist.
