Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627372, here are decompositions:

53 + 31627319 = 31627372
83 + 31627289 = 31627372
239 + 31627133 = 31627372
251 + 31627121 = 31627372
281 + 31627091 = 31627372
479 + 31626893 = 31627372
503 + 31626869 = 31627372
683 + 31626689 = 31627372

Showing the first eight; more decompositions exist.
