Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450132, here are decompositions:

29 + 31450103 = 31450132
71 + 31450061 = 31450132
89 + 31450043 = 31450132
101 + 31450031 = 31450132
431 + 31449701 = 31450132
443 + 31449689 = 31450132
503 + 31449629 = 31450132
521 + 31449611 = 31450132

Showing the first eight; more decompositions exist.
