Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486766, here are decompositions:

43 + 31486723 = 31486766
109 + 31486657 = 31486766
127 + 31486639 = 31486766
139 + 31486627 = 31486766
163 + 31486603 = 31486766
229 + 31486537 = 31486766
313 + 31486453 = 31486766
349 + 31486417 = 31486766

Showing the first eight; more decompositions exist.
