Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558076, here are decompositions:

3 + 31558073 = 31558076
13 + 31558063 = 31558076
19 + 31558057 = 31558076
37 + 31558039 = 31558076
79 + 31557997 = 31558076
139 + 31557937 = 31558076
157 + 31557919 = 31558076
373 + 31557703 = 31558076

Showing the first eight; more decompositions exist.
