Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450352, here are decompositions:

61 + 31450291 = 31450352
211 + 31450141 = 31450352
331 + 31450021 = 31450352
421 + 31449931 = 31450352
499 + 31449853 = 31450352
601 + 31449751 = 31450352
613 + 31449739 = 31450352
673 + 31449679 = 31450352

Showing the first eight; more decompositions exist.
