Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71190, here are decompositions:

19 + 71171 = 71190
23 + 71167 = 71190
29 + 71161 = 71190
37 + 71153 = 71190
43 + 71147 = 71190
47 + 71143 = 71190
61 + 71129 = 71190
71 + 71119 = 71190

Showing the first eight; more decompositions exist.
