Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712372, here are decompositions:

5 + 8712367 = 8712372
23 + 8712349 = 8712372
61 + 8712311 = 8712372
79 + 8712293 = 8712372
103 + 8712269 = 8712372
113 + 8712259 = 8712372
139 + 8712233 = 8712372
191 + 8712181 = 8712372

Showing the first eight; more decompositions exist.
