Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737442, here are decompositions:

19 + 8737423 = 8737442
193 + 8737249 = 8737442
199 + 8737243 = 8737442
313 + 8737129 = 8737442
331 + 8737111 = 8737442
379 + 8737063 = 8737442
421 + 8737021 = 8737442
499 + 8736943 = 8737442

Showing the first eight; more decompositions exist.
