Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499292, here are decompositions:

53 + 31499239 = 31499292
61 + 31499231 = 31499292
103 + 31499189 = 31499292
109 + 31499183 = 31499292
131 + 31499161 = 31499292
229 + 31499063 = 31499292
269 + 31499023 = 31499292
271 + 31499021 = 31499292

Showing the first eight; more decompositions exist.
