Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479052, here are decompositions:

83 + 31478969 = 31479052
569 + 31478483 = 31479052
641 + 31478411 = 31479052
653 + 31478399 = 31479052
659 + 31478393 = 31479052
701 + 31478351 = 31479052
719 + 31478333 = 31479052
743 + 31478309 = 31479052

Showing the first eight; more decompositions exist.
