Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479058, here are decompositions:

41 + 31479017 = 31479058
89 + 31478969 = 31479058
101 + 31478957 = 31479058
227 + 31478831 = 31479058
251 + 31478807 = 31479058
419 + 31478639 = 31479058
491 + 31478567 = 31479058
587 + 31478471 = 31479058

Showing the first eight; more decompositions exist.
