Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623802, here are decompositions:

5 + 31623797 = 31623802
71 + 31623731 = 31623802
101 + 31623701 = 31623802
131 + 31623671 = 31623802
179 + 31623623 = 31623802
281 + 31623521 = 31623802
293 + 31623509 = 31623802
311 + 31623491 = 31623802

Showing the first eight; more decompositions exist.
