Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720452, here are decompositions:

5 + 8720447 = 8720452
23 + 8720429 = 8720452
113 + 8720339 = 8720452
131 + 8720321 = 8720452
263 + 8720189 = 8720452
281 + 8720171 = 8720452
491 + 8719961 = 8720452
509 + 8719943 = 8720452

Showing the first eight; more decompositions exist.
