Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529044, here are decompositions:

47 + 31528997 = 31529044
191 + 31528853 = 31529044
233 + 31528811 = 31529044
293 + 31528751 = 31529044
347 + 31528697 = 31529044
431 + 31528613 = 31529044
593 + 31528451 = 31529044
761 + 31528283 = 31529044

Showing the first eight; more decompositions exist.
