Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720590, here are decompositions:

59 + 8720531 = 8720590
101 + 8720489 = 8720590
107 + 8720483 = 8720590
113 + 8720477 = 8720590
173 + 8720417 = 8720590
251 + 8720339 = 8720590
269 + 8720321 = 8720590
401 + 8720189 = 8720590

Showing the first eight; more decompositions exist.
