Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550654, here are decompositions:

43 + 31550611 = 31550654
61 + 31550593 = 31550654
67 + 31550587 = 31550654
73 + 31550581 = 31550654
97 + 31550557 = 31550654
193 + 31550461 = 31550654
283 + 31550371 = 31550654
367 + 31550287 = 31550654

Showing the first eight; more decompositions exist.
