Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479226, here are decompositions:

29 + 31479197 = 31479226
257 + 31478969 = 31479226
269 + 31478957 = 31479226
293 + 31478933 = 31479226
419 + 31478807 = 31479226
587 + 31478639 = 31479226
659 + 31478567 = 31479226
743 + 31478483 = 31479226

Showing the first eight; more decompositions exist.
