Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737212, here are decompositions:

13 + 8737199 = 8737212
19 + 8737193 = 8737212
59 + 8737153 = 8737212
73 + 8737139 = 8737212
83 + 8737129 = 8737212
101 + 8737111 = 8737212
139 + 8737073 = 8737212
149 + 8737063 = 8737212

Showing the first eight; more decompositions exist.
