Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722282, here are decompositions:

59 + 8722223 = 8722282
71 + 8722211 = 8722282
89 + 8722193 = 8722282
113 + 8722169 = 8722282
263 + 8722019 = 8722282
281 + 8722001 = 8722282
293 + 8721989 = 8722282
353 + 8721929 = 8722282

Showing the first eight; more decompositions exist.
