Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520292, here are decompositions:

59 + 31520233 = 31520292
113 + 31520179 = 31520292
151 + 31520141 = 31520292
173 + 31520119 = 31520292
233 + 31520059 = 31520292
263 + 31520029 = 31520292
281 + 31520011 = 31520292
283 + 31520009 = 31520292

Showing the first eight; more decompositions exist.
