Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71618, here are decompositions:

67 + 71551 = 71618
139 + 71479 = 71618
181 + 71437 = 71618
199 + 71419 = 71618
229 + 71389 = 71618
271 + 71347 = 71618
277 + 71341 = 71618
331 + 71287 = 71618

Showing the first eight; more decompositions exist.
