Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479122, here are decompositions:

61 + 31479061 = 31479122
139 + 31478983 = 31479122
163 + 31478959 = 31479122
211 + 31478911 = 31479122
271 + 31478851 = 31479122
421 + 31478701 = 31479122
523 + 31478599 = 31479122
541 + 31478581 = 31479122

Showing the first eight; more decompositions exist.
