Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478714, here are decompositions:

13 + 31478701 = 31478714
67 + 31478647 = 31478714
193 + 31478521 = 31478714
313 + 31478401 = 31478714
373 + 31478341 = 31478714
541 + 31478173 = 31478714
691 + 31478023 = 31478714
991 + 31477723 = 31478714

Showing the first eight; more decompositions exist.
