Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712742, here are decompositions:

29 + 8712713 = 8712742
41 + 8712701 = 8712742
113 + 8712629 = 8712742
131 + 8712611 = 8712742
251 + 8712491 = 8712742
419 + 8712323 = 8712742
431 + 8712311 = 8712742
449 + 8712293 = 8712742

Showing the first eight; more decompositions exist.
