Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479544, here are decompositions:

3 + 31479541 = 31479544
53 + 31479491 = 31479544
293 + 31479251 = 31479544
347 + 31479197 = 31479544
443 + 31479101 = 31479544
461 + 31479083 = 31479544
587 + 31478957 = 31479544
977 + 31478567 = 31479544

Showing the first eight; more decompositions exist.
