Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452028, here are decompositions:

29 + 31451999 = 31452028
59 + 31451969 = 31452028
191 + 31451837 = 31452028
227 + 31451801 = 31452028
317 + 31451711 = 31452028
431 + 31451597 = 31452028
449 + 31451579 = 31452028
467 + 31451561 = 31452028

Showing the first eight; more decompositions exist.
