Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450654, here are decompositions:

41 + 31450613 = 31450654
71 + 31450583 = 31450654
113 + 31450541 = 31450654
167 + 31450487 = 31450654
227 + 31450427 = 31450654
233 + 31450421 = 31450654
383 + 31450271 = 31450654
491 + 31450163 = 31450654

Showing the first eight; more decompositions exist.
