Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474652, here are decompositions:

103 + 31474549 = 31474652
151 + 31474501 = 31474652
163 + 31474489 = 31474652
229 + 31474423 = 31474652
439 + 31474213 = 31474652
523 + 31474129 = 31474652
541 + 31474111 = 31474652
619 + 31474033 = 31474652

Showing the first eight; more decompositions exist.
