Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720236, here are decompositions:

3 + 8720233 = 8720236
47 + 8720189 = 8720236
59 + 8720177 = 8720236
149 + 8720087 = 8720236
179 + 8720057 = 8720236
293 + 8719943 = 8720236
389 + 8719847 = 8720236
419 + 8719817 = 8720236

Showing the first eight; more decompositions exist.
