Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479222, here are decompositions:

139 + 31479083 = 31479222
149 + 31479073 = 31479222
191 + 31479031 = 31479222
239 + 31478983 = 31479222
263 + 31478959 = 31479222
311 + 31478911 = 31479222
503 + 31478719 = 31479222
521 + 31478701 = 31479222

Showing the first eight; more decompositions exist.
