Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720362, here are decompositions:

23 + 8720339 = 8720362
41 + 8720321 = 8720362
173 + 8720189 = 8720362
191 + 8720171 = 8720362
251 + 8720111 = 8720362
281 + 8720081 = 8720362
401 + 8719961 = 8720362
419 + 8719943 = 8720362

Showing the first eight; more decompositions exist.
