Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627282, here are decompositions:

131 + 31627151 = 31627282
149 + 31627133 = 31627282
191 + 31627091 = 31627282
383 + 31626899 = 31627282
389 + 31626893 = 31627282
443 + 31626839 = 31627282
593 + 31626689 = 31627282
719 + 31626563 = 31627282

Showing the first eight; more decompositions exist.
