Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516070, here are decompositions:

43 + 31516027 = 31516070
139 + 31515931 = 31516070
151 + 31515919 = 31516070
307 + 31515763 = 31516070
337 + 31515733 = 31516070
367 + 31515703 = 31516070
373 + 31515697 = 31516070
463 + 31515607 = 31516070

Showing the first eight; more decompositions exist.
