Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479126, here are decompositions:

43 + 31479083 = 31479126
53 + 31479073 = 31479126
109 + 31479017 = 31479126
157 + 31478969 = 31479126
167 + 31478959 = 31479126
193 + 31478933 = 31479126
389 + 31478737 = 31479126
479 + 31478647 = 31479126

Showing the first eight; more decompositions exist.
