Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188102, here are decompositions:

73 + 188029 = 188102
139 + 187963 = 188102
151 + 187951 = 188102
181 + 187921 = 188102
193 + 187909 = 188102
241 + 187861 = 188102
433 + 187669 = 188102
463 + 187639 = 188102

Showing the first eight; more decompositions exist.
