Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537162, here are decompositions:

11 + 31537151 = 31537162
29 + 31537133 = 31537162
113 + 31537049 = 31537162
179 + 31536983 = 31537162
389 + 31536773 = 31537162
431 + 31536731 = 31537162
443 + 31536719 = 31537162
641 + 31536521 = 31537162

Showing the first eight; more decompositions exist.
