Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454770, here are decompositions:

29 + 31454741 = 31454770
89 + 31454681 = 31454770
101 + 31454669 = 31454770
257 + 31454513 = 31454770
419 + 31454351 = 31454770
449 + 31454321 = 31454770
521 + 31454249 = 31454770
569 + 31454201 = 31454770

Showing the first eight; more decompositions exist.
