Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558762, here are decompositions:

3 + 31558759 = 31558762
29 + 31558733 = 31558762
89 + 31558673 = 31558762
113 + 31558649 = 31558762
233 + 31558529 = 31558762
293 + 31558469 = 31558762
383 + 31558379 = 31558762
479 + 31558283 = 31558762

Showing the first eight; more decompositions exist.
