Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737172, here are decompositions:

19 + 8737153 = 8737172
43 + 8737129 = 8737172
61 + 8737111 = 8737172
109 + 8737063 = 8737172
151 + 8737021 = 8737172
229 + 8736943 = 8737172
373 + 8736799 = 8737172
541 + 8736631 = 8737172

Showing the first eight; more decompositions exist.
