Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516274, here are decompositions:

37 + 31516237 = 31516274
73 + 31516201 = 31516274
151 + 31516123 = 31516274
193 + 31516081 = 31516274
337 + 31515937 = 31516274
541 + 31515733 = 31516274
571 + 31515703 = 31516274
577 + 31515697 = 31516274

Showing the first eight; more decompositions exist.
