Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537062, here are decompositions:

13 + 31537049 = 31537062
19 + 31537043 = 31537062
23 + 31537039 = 31537062
59 + 31537003 = 31537062
61 + 31537001 = 31537062
71 + 31536991 = 31537062
79 + 31536983 = 31537062
103 + 31536959 = 31537062

Showing the first eight; more decompositions exist.
