Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530262, here are decompositions:

59 + 31530203 = 31530262
89 + 31530173 = 31530262
233 + 31530029 = 31530262
293 + 31529969 = 31530262
419 + 31529843 = 31530262
443 + 31529819 = 31530262
479 + 31529783 = 31530262
593 + 31529669 = 31530262

Showing the first eight; more decompositions exist.
