Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168190, here are decompositions:

47 + 168143 = 168190
101 + 168089 = 168190
107 + 168083 = 168190
167 + 168023 = 168190
311 + 167879 = 168190
317 + 167873 = 168190
389 + 167801 = 168190
419 + 167771 = 168190

Showing the first eight; more decompositions exist.
