Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720374, here are decompositions:

53 + 8720321 = 8720374
197 + 8720177 = 8720374
263 + 8720111 = 8720374
293 + 8720081 = 8720374
317 + 8720057 = 8720374
347 + 8720027 = 8720374
431 + 8719943 = 8720374
557 + 8719817 = 8720374

Showing the first eight; more decompositions exist.
