Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479062, here are decompositions:

31 + 31479031 = 31479062
61 + 31479001 = 31479062
79 + 31478983 = 31479062
103 + 31478959 = 31479062
151 + 31478911 = 31479062
211 + 31478851 = 31479062
463 + 31478599 = 31479062
541 + 31478521 = 31479062

Showing the first eight; more decompositions exist.
