Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712442, here are decompositions:

71 + 8712371 = 8712442
131 + 8712311 = 8712442
149 + 8712293 = 8712442
173 + 8712269 = 8712442
269 + 8712173 = 8712442
293 + 8712149 = 8712442
383 + 8712059 = 8712442
491 + 8711951 = 8712442

Showing the first eight; more decompositions exist.
