Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733820, here are decompositions:

83 + 8733737 = 8733820
89 + 8733731 = 8733820
101 + 8733719 = 8733820
107 + 8733713 = 8733820
113 + 8733707 = 8733820
269 + 8733551 = 8733820
353 + 8733467 = 8733820
401 + 8733419 = 8733820

Showing the first eight; more decompositions exist.
