Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738900, here are decompositions:

19 + 8738881 = 8738900
61 + 8738839 = 8738900
193 + 8738707 = 8738900
229 + 8738671 = 8738900
241 + 8738659 = 8738900
367 + 8738533 = 8738900
409 + 8738491 = 8738900
463 + 8738437 = 8738900

Showing the first eight; more decompositions exist.
