Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451362, here are decompositions:

101 + 31451261 = 31451362
191 + 31451171 = 31451362
251 + 31451111 = 31451362
401 + 31450961 = 31451362
521 + 31450841 = 31451362
599 + 31450763 = 31451362
641 + 31450721 = 31451362
743 + 31450619 = 31451362

Showing the first eight; more decompositions exist.
