Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750442, here are decompositions:

13 + 8750429 = 8750442
73 + 8750369 = 8750442
79 + 8750363 = 8750442
101 + 8750341 = 8750442
109 + 8750333 = 8750442
149 + 8750293 = 8750442
193 + 8750249 = 8750442
199 + 8750243 = 8750442

Showing the first eight; more decompositions exist.
