Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537030, here are decompositions:

3 + 31537027 = 31537030
29 + 31537001 = 31537030
47 + 31536983 = 31537030
71 + 31536959 = 31537030
113 + 31536917 = 31537030
167 + 31536863 = 31537030
257 + 31536773 = 31537030
311 + 31536719 = 31537030

Showing the first eight; more decompositions exist.
