Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479050, here are decompositions:

19 + 31479031 = 31479050
67 + 31478983 = 31479050
139 + 31478911 = 31479050
199 + 31478851 = 31479050
313 + 31478737 = 31479050
331 + 31478719 = 31479050
349 + 31478701 = 31479050
457 + 31478593 = 31479050

Showing the first eight; more decompositions exist.
